Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80170, here are decompositions:

  • 3 + 80167 = 80170
  • 17 + 80153 = 80170
  • 23 + 80147 = 80170
  • 29 + 80141 = 80170
  • 59 + 80111 = 80170
  • 131 + 80039 = 80170
  • 149 + 80021 = 80170
  • 173 + 79997 = 80170

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 80170 first appears in π at position 755,869 of the decimal expansion (the 755,869ordinal-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.
