Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40080, here are decompositions:

  • 17 + 40063 = 40080
  • 41 + 40039 = 40080
  • 43 + 40037 = 40080
  • 67 + 40013 = 40080
  • 71 + 40009 = 40080
  • 97 + 39983 = 40080
  • 101 + 39979 = 40080
  • 109 + 39971 = 40080

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40080 first appears in π at position 73,442 of the decimal expansion (the 73,442ordinal-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.
