Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43578, here are decompositions:

  • 5 + 43573 = 43578
  • 37 + 43541 = 43578
  • 61 + 43517 = 43578
  • 79 + 43499 = 43578
  • 97 + 43481 = 43578
  • 127 + 43451 = 43578
  • 137 + 43441 = 43578
  • 151 + 43427 = 43578

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 43578 first appears in π at position 9,432 of the decimal expansion (the 9,432ordinal-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.
