Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544892, here are decompositions:

  • 13 + 31544879 = 31544892
  • 73 + 31544819 = 31544892
  • 109 + 31544783 = 31544892
  • 173 + 31544719 = 31544892
  • 179 + 31544713 = 31544892
  • 331 + 31544561 = 31544892
  • 349 + 31544543 = 31544892
  • 359 + 31544533 = 31544892

Showing the first eight; more decompositions exist.
