Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557500, here are decompositions:

  • 11 + 557489 = 557500
  • 17 + 557483 = 557500
  • 131 + 557369 = 557500
  • 179 + 557321 = 557500
  • 191 + 557309 = 557500
  • 197 + 557303 = 557500
  • 227 + 557273 = 557500
  • 239 + 557261 = 557500

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 557,500 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 557500 first appears in π at position 289,235 of the decimal expansion (the 289,235ordinal-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.
