Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74400, here are decompositions:

  • 17 + 74383 = 74400
  • 19 + 74381 = 74400
  • 23 + 74377 = 74400
  • 37 + 74363 = 74400
  • 43 + 74357 = 74400
  • 47 + 74353 = 74400
  • 83 + 74317 = 74400
  • 89 + 74311 = 74400

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 74400 first appears in π at position 39,311 of the decimal expansion (the 39,311ordinal-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.
