Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5578, here are decompositions:

  • 5 + 5573 = 5578
  • 47 + 5531 = 5578
  • 59 + 5519 = 5578
  • 71 + 5507 = 5578
  • 101 + 5477 = 5578
  • 107 + 5471 = 5578
  • 137 + 5441 = 5578
  • 179 + 5399 = 5578

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 5578 first appears in π at position 4,016 of the decimal expansion (the 4,016ordinal-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.
