Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544590, here are decompositions:

  • 3 + 31544587 = 31544590
  • 17 + 31544573 = 31544590
  • 29 + 31544561 = 31544590
  • 47 + 31544543 = 31544590
  • 59 + 31544531 = 31544590
  • 173 + 31544417 = 31544590
  • 197 + 31544393 = 31544590
  • 227 + 31544363 = 31544590

Showing the first eight; more decompositions exist.
