Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555172, here are decompositions:

  • 5 + 555167 = 555172
  • 29 + 555143 = 555172
  • 53 + 555119 = 555172
  • 89 + 555083 = 555172
  • 131 + 555041 = 555172
  • 281 + 554891 = 555172
  • 383 + 554789 = 555172
  • 419 + 554753 = 555172

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 555,172 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 555172 first appears in π at position 926,677 of the decimal expansion (the 926,677ordinal-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.
