Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147470658, here are decompositions:

  • 31 + 2147470627 = 2147470658
  • 61 + 2147470597 = 2147470658
  • 79 + 2147470579 = 2147470658
  • 127 + 2147470531 = 2147470658
  • 331 + 2147470327 = 2147470658
  • 409 + 2147470249 = 2147470658
  • 547 + 2147470111 = 2147470658
  • 577 + 2147470081 = 2147470658

Showing the first eight; more decompositions exist.
