Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16458, here are decompositions:

  • 5 + 16453 = 16458
  • 7 + 16451 = 16458
  • 11 + 16447 = 16458
  • 31 + 16427 = 16458
  • 37 + 16421 = 16458
  • 41 + 16417 = 16458
  • 47 + 16411 = 16458
  • 89 + 16369 = 16458

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16458 first appears in π at position 44,385 of the decimal expansion (the 44,385ordinal-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.
