Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986578, here are decompositions:

  • 11 + 986567 = 986578
  • 59 + 986519 = 986578
  • 71 + 986507 = 986578
  • 101 + 986477 = 986578
  • 107 + 986471 = 986578
  • 149 + 986429 = 986578
  • 167 + 986411 = 986578
  • 227 + 986351 = 986578

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 986,578 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 986578 first appears in π at position 617,489 of the decimal expansion (the 617,489ordinal-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.
