Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80002, here are decompositions:

  • 3 + 79999 = 80002
  • 5 + 79997 = 80002
  • 23 + 79979 = 80002
  • 29 + 79973 = 80002
  • 59 + 79943 = 80002
  • 101 + 79901 = 80002
  • 113 + 79889 = 80002
  • 173 + 79829 = 80002

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 80002 first appears in π at position 22,758 of the decimal expansion (the 22,758ordinal-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.
