Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557278, here are decompositions:

  • 5 + 557273 = 557278
  • 17 + 557261 = 557278
  • 191 + 557087 = 557278
  • 251 + 557027 = 557278
  • 257 + 557021 = 557278
  • 311 + 556967 = 557278
  • 347 + 556931 = 557278
  • 419 + 556859 = 557278

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 557,278 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 557278 first appears in π at position 298,476 of the decimal expansion (the 298,476ordinal-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.
