Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544582, here are decompositions:

  • 31 + 31544551 = 31544582
  • 73 + 31544509 = 31544582
  • 211 + 31544371 = 31544582
  • 271 + 31544311 = 31544582
  • 541 + 31544041 = 31544582
  • 571 + 31544011 = 31544582
  • 709 + 31543873 = 31544582
  • 739 + 31543843 = 31544582

Showing the first eight; more decompositions exist.
