Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1574, here are decompositions:

  • 3 + 1571 = 1574
  • 7 + 1567 = 1574
  • 31 + 1543 = 1574
  • 43 + 1531 = 1574
  • 103 + 1471 = 1574
  • 127 + 1447 = 1574
  • 151 + 1423 = 1574
  • 193 + 1381 = 1574

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1574 first appears in π at position 19,323 of the decimal expansion (the 19,323ordinal-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.
