Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509186, here are decompositions:

  • 37 + 509149 = 509186
  • 163 + 509023 = 509186
  • 199 + 508987 = 509186
  • 229 + 508957 = 509186
  • 277 + 508909 = 509186
  • 283 + 508903 = 509186
  • 397 + 508789 = 509186
  • 607 + 508579 = 509186

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 509,186 and was likely granted around 1893.

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

Position in π

The digit sequence 509186 first appears in π at position 424,644 of the decimal expansion (the 424,644ordinal-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.
