Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988868, here are decompositions:

  • 7 + 988861 = 988868
  • 19 + 988849 = 988868
  • 31 + 988837 = 988868
  • 79 + 988789 = 988868
  • 109 + 988759 = 988868
  • 157 + 988711 = 988868
  • 277 + 988591 = 988868
  • 367 + 988501 = 988868

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 988,868 and was likely granted around 1911.

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

Position in π

The digit sequence 988868 first appears in π at position 4,984 of the decimal expansion (the 4,984ordinal-suffix:th 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.
