Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561442, here are decompositions:

  • 3 + 561439 = 561442
  • 23 + 561419 = 561442
  • 53 + 561389 = 561442
  • 83 + 561359 = 561442
  • 191 + 561251 = 561442
  • 251 + 561191 = 561442
  • 269 + 561173 = 561442
  • 281 + 561161 = 561442

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 561,442 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 561442 first appears in π at position 957,821 of the decimal expansion (the 957,821ordinal-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.
