Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49280, here are decompositions:

  • 3 + 49277 = 49280
  • 19 + 49261 = 49280
  • 73 + 49207 = 49280
  • 79 + 49201 = 49280
  • 103 + 49177 = 49280
  • 109 + 49171 = 49280
  • 157 + 49123 = 49280
  • 163 + 49117 = 49280

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 49280 first appears in π at position 19,879 of the decimal expansion (the 19,879ordinal-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.
