Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1486, here are decompositions:

  • 3 + 1483 = 1486
  • 5 + 1481 = 1486
  • 47 + 1439 = 1486
  • 53 + 1433 = 1486
  • 59 + 1427 = 1486
  • 113 + 1373 = 1486
  • 167 + 1319 = 1486
  • 179 + 1307 = 1486

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1486 first appears in π at position 7,497 of the decimal expansion (the 7,497ordinal-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.
