Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80802, here are decompositions:

  • 13 + 80789 = 80802
  • 19 + 80783 = 80802
  • 23 + 80779 = 80802
  • 41 + 80761 = 80802
  • 53 + 80749 = 80802
  • 89 + 80713 = 80802
  • 101 + 80701 = 80802
  • 131 + 80671 = 80802

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 80802 first appears in π at position 181,398 of the decimal expansion (the 181,398ordinal-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.
