Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80012, here are decompositions:

  • 13 + 79999 = 80012
  • 73 + 79939 = 80012
  • 109 + 79903 = 80012
  • 139 + 79873 = 80012
  • 151 + 79861 = 80012
  • 199 + 79813 = 80012
  • 211 + 79801 = 80012
  • 313 + 79699 = 80012

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 80012 first appears in π at position 15,455 of the decimal expansion (the 15,455ordinal-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.
