Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555618, here are decompositions:

  • 29 + 555589 = 555618
  • 61 + 555557 = 555618
  • 97 + 555521 = 555618
  • 127 + 555491 = 555618
  • 131 + 555487 = 555618
  • 157 + 555461 = 555618
  • 179 + 555439 = 555618
  • 197 + 555421 = 555618

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 555,618 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 555618 first appears in π at position 47,546 of the decimal expansion (the 47,546ordinal-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.
