Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473756, here are decompositions:

  • 23 + 31473733 = 31473756
  • 53 + 31473703 = 31473756
  • 157 + 31473599 = 31473756
  • 163 + 31473593 = 31473756
  • 173 + 31473583 = 31473756
  • 227 + 31473529 = 31473756
  • 233 + 31473523 = 31473756
  • 269 + 31473487 = 31473756

Showing the first eight; more decompositions exist.
