Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80006, here are decompositions:

  • 7 + 79999 = 80006
  • 19 + 79987 = 80006
  • 67 + 79939 = 80006
  • 103 + 79903 = 80006
  • 139 + 79867 = 80006
  • 163 + 79843 = 80006
  • 193 + 79813 = 80006
  • 229 + 79777 = 80006

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 80006 first appears in π at position 42,902 of the decimal expansion (the 42,902ordinal-suffix:nd 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.
