Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 566442, here are decompositions:

  • 5 + 566437 = 566442
  • 11 + 566431 = 566442
  • 13 + 566429 = 566442
  • 29 + 566413 = 566442
  • 131 + 566311 = 566442
  • 211 + 566231 = 566442
  • 229 + 566213 = 566442
  • 241 + 566201 = 566442

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 566,442 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 566442 first appears in π at position 672,784 of the decimal expansion (the 672,784ordinal-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.
