Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557720, here are decompositions:

  • 3 + 557717 = 557720
  • 109 + 557611 = 557720
  • 199 + 557521 = 557720
  • 271 + 557449 = 557720
  • 277 + 557443 = 557720
  • 349 + 557371 = 557720
  • 439 + 557281 = 557720
  • 523 + 557197 = 557720

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 557,720 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 557720 first appears in π at position 711,406 of the decimal expansion (the 711,406ordinal-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.
