Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80212, here are decompositions:

  • 3 + 80209 = 80212
  • 5 + 80207 = 80212
  • 59 + 80153 = 80212
  • 71 + 80141 = 80212
  • 101 + 80111 = 80212
  • 173 + 80039 = 80212
  • 191 + 80021 = 80212
  • 233 + 79979 = 80212

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 80212 first appears in π at position 65,476 of the decimal expansion (the 65,476ordinal-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.
