Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718090, here are decompositions:

  • 47 + 8718043 = 8718090
  • 79 + 8718011 = 8718090
  • 83 + 8718007 = 8718090
  • 97 + 8717993 = 8718090
  • 103 + 8717987 = 8718090
  • 109 + 8717981 = 8718090
  • 127 + 8717963 = 8718090
  • 131 + 8717959 = 8718090

Showing the first eight; more decompositions exist.
