Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155598, here are decompositions:

  • 5 + 155593 = 155598
  • 17 + 155581 = 155598
  • 19 + 155579 = 155598
  • 29 + 155569 = 155598
  • 41 + 155557 = 155598
  • 59 + 155539 = 155598
  • 61 + 155537 = 155598
  • 89 + 155509 = 155598

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 155,598 and was likely granted around 1873.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 155598 first appears in π at position 564,971 of the decimal expansion (the 564,971ordinal-suffix:st 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.
