Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 571518, here are decompositions:

  • 41 + 571477 = 571518
  • 47 + 571471 = 571518
  • 109 + 571409 = 571518
  • 137 + 571381 = 571518
  • 149 + 571369 = 571518
  • 179 + 571339 = 571518
  • 197 + 571321 = 571518
  • 239 + 571279 = 571518

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 571,518 and was likely granted around 1896.

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

Position in π

The digit sequence 571518 first appears in π at position 650,955 of the decimal expansion (the 650,955ordinal-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.
