Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561524, here are decompositions:

  • 3 + 561521 = 561524
  • 151 + 561373 = 561524
  • 157 + 561367 = 561524
  • 181 + 561343 = 561524
  • 211 + 561313 = 561524
  • 421 + 561103 = 561524
  • 433 + 561091 = 561524
  • 463 + 561061 = 561524

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 561,524 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 561524 first appears in π at position 21,469 of the decimal expansion (the 21,469ordinal-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.
