Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544718, here are decompositions:

  • 5 + 31544713 = 31544718
  • 61 + 31544657 = 31544718
  • 131 + 31544587 = 31544718
  • 157 + 31544561 = 31544718
  • 167 + 31544551 = 31544718
  • 347 + 31544371 = 31544718
  • 421 + 31544297 = 31544718
  • 547 + 31544171 = 31544718

Showing the first eight; more decompositions exist.
