Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155706, here are decompositions:

  • 7 + 155699 = 155706
  • 13 + 155693 = 155706
  • 17 + 155689 = 155706
  • 43 + 155663 = 155706
  • 53 + 155653 = 155706
  • 79 + 155627 = 155706
  • 97 + 155609 = 155706
  • 107 + 155599 = 155706

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 155,706 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 155706 first appears in π at position 241,589 of the decimal expansion (the 241,589ordinal-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.
