Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 566428, here are decompositions:

  • 11 + 566417 = 566428
  • 41 + 566387 = 566428
  • 197 + 566231 = 566428
  • 227 + 566201 = 566428
  • 431 + 565997 = 566428
  • 449 + 565979 = 566428
  • 491 + 565937 = 566428
  • 509 + 565919 = 566428

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 566,428 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 566428 first appears in π at position 586,908 of the decimal expansion (the 586,908ordinal-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.
