Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555428, here are decompositions:

  • 7 + 555421 = 555428
  • 37 + 555391 = 555428
  • 67 + 555361 = 555428
  • 79 + 555349 = 555428
  • 127 + 555301 = 555428
  • 151 + 555277 = 555428
  • 331 + 555097 = 555428
  • 337 + 555091 = 555428

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 555,428 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 555428 first appears in π at position 552,014 of the decimal expansion (the 552,014ordinal-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.
