Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80306, here are decompositions:

  • 19 + 80287 = 80306
  • 43 + 80263 = 80306
  • 67 + 80239 = 80306
  • 73 + 80233 = 80306
  • 97 + 80209 = 80306
  • 139 + 80167 = 80306
  • 157 + 80149 = 80306
  • 199 + 80107 = 80306

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 80306 first appears in π at position 318,548 of the decimal expansion (the 318,548ordinal-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.
