Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404964, here are decompositions:

  • 7 + 2147404957 = 2147404964
  • 31 + 2147404933 = 2147404964
  • 73 + 2147404891 = 2147404964
  • 193 + 2147404771 = 2147404964
  • 571 + 2147404393 = 2147404964
  • 811 + 2147404153 = 2147404964
  • 823 + 2147404141 = 2147404964
  • 1291 + 2147403673 = 2147404964

Showing the first eight; more decompositions exist.
