Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987654, here are decompositions:

  • 23 + 987631 = 987654
  • 47 + 987607 = 987654
  • 61 + 987593 = 987654
  • 67 + 987587 = 987654
  • 113 + 987541 = 987654
  • 131 + 987523 = 987654
  • 163 + 987491 = 987654
  • 181 + 987473 = 987654

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 987,654 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 987654 first appears in π at position 948,943 of the decimal expansion (the 948,943ordinal-suffix:rd 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.
