Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537870, here are decompositions:

  • 17 + 537853 = 537870
  • 23 + 537847 = 537870
  • 29 + 537841 = 537870
  • 59 + 537811 = 537870
  • 83 + 537787 = 537870
  • 89 + 537781 = 537870
  • 97 + 537773 = 537870
  • 101 + 537769 = 537870

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 537,870 and was likely granted around 1894.

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

Position in π

The digit sequence 537870 first appears in π at position 97,812 of the decimal expansion (the 97,812ordinal-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.
