Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561844, here are decompositions:

  • 5 + 561839 = 561844
  • 47 + 561797 = 561844
  • 83 + 561761 = 561844
  • 131 + 561713 = 561844
  • 293 + 561551 = 561844
  • 383 + 561461 = 561844
  • 467 + 561377 = 561844
  • 593 + 561251 = 561844

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 561,844 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 561844 first appears in π at position 687,391 of the decimal expansion (the 687,391ordinal-suffix:st 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.
