Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557530, here are decompositions:

  • 11 + 557519 = 557530
  • 41 + 557489 = 557530
  • 47 + 557483 = 557530
  • 107 + 557423 = 557530
  • 191 + 557339 = 557530
  • 227 + 557303 = 557530
  • 257 + 557273 = 557530
  • 269 + 557261 = 557530

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 557,530 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 557530 first appears in π at position 539,087 of the decimal expansion (the 539,087ordinal-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.
