Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80980, here are decompositions:

  • 17 + 80963 = 80980
  • 47 + 80933 = 80980
  • 71 + 80909 = 80980
  • 83 + 80897 = 80980
  • 131 + 80849 = 80980
  • 149 + 80831 = 80980
  • 191 + 80789 = 80980
  • 197 + 80783 = 80980

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 80980 first appears in π at position 26,162 of the decimal expansion (the 26,162ordinal-suffix:nd 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.
