Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147470628, here are decompositions:

  • 31 + 2147470597 = 2147470628
  • 97 + 2147470531 = 2147470628
  • 379 + 2147470249 = 2147470628
  • 547 + 2147470081 = 2147470628
  • 571 + 2147470057 = 2147470628
  • 601 + 2147470027 = 2147470628
  • 811 + 2147469817 = 2147470628
  • 991 + 2147469637 = 2147470628

Showing the first eight; more decompositions exist.
