Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473624, here are decompositions:

  • 31 + 31473593 = 31473624
  • 41 + 31473583 = 31473624
  • 43 + 31473581 = 31473624
  • 101 + 31473523 = 31473624
  • 137 + 31473487 = 31473624
  • 167 + 31473457 = 31473624
  • 211 + 31473413 = 31473624
  • 227 + 31473397 = 31473624

Showing the first eight; more decompositions exist.
