Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707090, here are decompositions:

  • 53 + 8707037 = 8707090
  • 59 + 8707031 = 8707090
  • 83 + 8707007 = 8707090
  • 107 + 8706983 = 8707090
  • 137 + 8706953 = 8707090
  • 257 + 8706833 = 8707090
  • 347 + 8706743 = 8707090
  • 383 + 8706707 = 8707090

Showing the first eight; more decompositions exist.
