Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80188, here are decompositions:

  • 11 + 80177 = 80188
  • 41 + 80147 = 80188
  • 47 + 80141 = 80188
  • 137 + 80051 = 80188
  • 149 + 80039 = 80188
  • 167 + 80021 = 80188
  • 191 + 79997 = 80188
  • 281 + 79907 = 80188

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 80188 first appears in π at position 29,161 of the decimal expansion (the 29,161ordinal-suffix:st 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.
