Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40590, here are decompositions:

  • 7 + 40583 = 40590
  • 13 + 40577 = 40590
  • 31 + 40559 = 40590
  • 47 + 40543 = 40590
  • 59 + 40531 = 40590
  • 61 + 40529 = 40590
  • 71 + 40519 = 40590
  • 83 + 40507 = 40590

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40590 first appears in π at position 21,077 of the decimal expansion (the 21,077ordinal-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.
