Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557028, here are decompositions:

  • 7 + 557021 = 557028
  • 11 + 557017 = 557028
  • 29 + 556999 = 557028
  • 41 + 556987 = 557028
  • 47 + 556981 = 557028
  • 61 + 556967 = 557028
  • 71 + 556957 = 557028
  • 89 + 556939 = 557028

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 557,028 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 557028 first appears in π at position 910,311 of the decimal expansion (the 910,311ordinal-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.
