Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74280, here are decompositions:

  • 23 + 74257 = 74280
  • 61 + 74219 = 74280
  • 71 + 74209 = 74280
  • 79 + 74201 = 74280
  • 83 + 74197 = 74280
  • 103 + 74177 = 74280
  • 113 + 74167 = 74280
  • 131 + 74149 = 74280

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 74280 first appears in π at position 41,768 of the decimal expansion (the 41,768ordinal-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.
