Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658988, here are decompositions:

  • 5 + 8658983 = 8658988
  • 11 + 8658977 = 8658988
  • 29 + 8658959 = 8658988
  • 47 + 8658941 = 8658988
  • 101 + 8658887 = 8658988
  • 311 + 8658677 = 8658988
  • 419 + 8658569 = 8658988
  • 461 + 8658527 = 8658988

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,658,988 and was likely granted around 2014.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 8658988 first appears in π at position 693,432 of the decimal expansion (the 693,432ordinal-suffix:nd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
