Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578988, here are decompositions:

  • 17 + 578971 = 578988
  • 29 + 578959 = 578988
  • 31 + 578957 = 578988
  • 71 + 578917 = 578988
  • 107 + 578881 = 578988
  • 127 + 578861 = 578988
  • 131 + 578857 = 578988
  • 149 + 578839 = 578988

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 578,988 and was likely granted around 1896.

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

Position in π

The digit sequence 578988 first appears in π at position 205,239 of the decimal expansion (the 205,239ordinal-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.
