Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542718, here are decompositions:

  • 41 + 31542677 = 31542718
  • 59 + 31542659 = 31542718
  • 131 + 31542587 = 31542718
  • 239 + 31542479 = 31542718
  • 281 + 31542437 = 31542718
  • 359 + 31542359 = 31542718
  • 521 + 31542197 = 31542718
  • 569 + 31542149 = 31542718

Showing the first eight; more decompositions exist.
