Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185574, here are decompositions:

  • 5 + 185569 = 185574
  • 7 + 185567 = 185574
  • 17 + 185557 = 185574
  • 23 + 185551 = 185574
  • 31 + 185543 = 185574
  • 41 + 185533 = 185574
  • 43 + 185531 = 185574
  • 47 + 185527 = 185574

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 185,574 and was likely granted around 1875.

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

Position in π

The digit sequence 185574 first appears in π at position 37,700 of the decimal expansion (the 37,700ordinal-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.
