Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74578, here are decompositions:

  • 5 + 74573 = 74578
  • 11 + 74567 = 74578
  • 17 + 74561 = 74578
  • 47 + 74531 = 74578
  • 71 + 74507 = 74578
  • 89 + 74489 = 74578
  • 107 + 74471 = 74578
  • 137 + 74441 = 74578

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 74578 first appears in π at position 163,866 of the decimal expansion (the 163,866ordinal-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.
