Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80194, here are decompositions:

  • 3 + 80191 = 80194
  • 17 + 80177 = 80194
  • 41 + 80153 = 80194
  • 47 + 80147 = 80194
  • 53 + 80141 = 80194
  • 83 + 80111 = 80194
  • 173 + 80021 = 80194
  • 197 + 79997 = 80194

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 80194 first appears in π at position 108,410 of the decimal expansion (the 108,410ordinal-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.
