Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561590, here are decompositions:

  • 31 + 561559 = 561590
  • 37 + 561553 = 561590
  • 61 + 561529 = 561590
  • 151 + 561439 = 561590
  • 181 + 561409 = 561590
  • 223 + 561367 = 561590
  • 277 + 561313 = 561590
  • 283 + 561307 = 561590

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 561,590 and was likely granted around 1895.

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

Position in π

The digit sequence 561590 first appears in π at position 369,630 of the decimal expansion (the 369,630ordinal-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.
