Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576310, here are decompositions:

  • 43 + 31576267 = 31576310
  • 79 + 31576231 = 31576310
  • 109 + 31576201 = 31576310
  • 193 + 31576117 = 31576310
  • 223 + 31576087 = 31576310
  • 307 + 31576003 = 31576310
  • 373 + 31575937 = 31576310
  • 433 + 31575877 = 31576310

Showing the first eight; more decompositions exist.
