Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41280, here are decompositions:

  • 11 + 41269 = 41280
  • 17 + 41263 = 41280
  • 23 + 41257 = 41280
  • 37 + 41243 = 41280
  • 47 + 41233 = 41280
  • 53 + 41227 = 41280
  • 59 + 41221 = 41280
  • 67 + 41213 = 41280

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 41280 first appears in π at position 46,723 of the decimal expansion (the 46,723ordinal-suffix:rd 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.
