Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985520, here are decompositions:

  • 37 + 985483 = 985520
  • 73 + 985447 = 985520
  • 103 + 985417 = 985520
  • 181 + 985339 = 985520
  • 229 + 985291 = 985520
  • 241 + 985279 = 985520
  • 307 + 985213 = 985520
  • 457 + 985063 = 985520

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 985,520 and was likely granted around 1910.

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

Position in π

The digit sequence 985520 first appears in π at position 368,755 of the decimal expansion (the 368,755ordinal-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.
