Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473528, here are decompositions:

  • 5 + 31473523 = 31473528
  • 41 + 31473487 = 31473528
  • 71 + 31473457 = 31473528
  • 131 + 31473397 = 31473528
  • 197 + 31473331 = 31473528
  • 277 + 31473251 = 31473528
  • 311 + 31473217 = 31473528
  • 337 + 31473191 = 31473528

Showing the first eight; more decompositions exist.
