Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567234, here are decompositions:

  • 3 + 31567231 = 31567234
  • 191 + 31567043 = 31567234
  • 431 + 31566803 = 31567234
  • 521 + 31566713 = 31567234
  • 761 + 31566473 = 31567234
  • 857 + 31566377 = 31567234
  • 887 + 31566347 = 31567234
  • 947 + 31566287 = 31567234

Showing the first eight; more decompositions exist.
