Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472726, here are decompositions:

  • 13 + 2147472713 = 2147472726
  • 29 + 2147472697 = 2147472726
  • 37 + 2147472689 = 2147472726
  • 43 + 2147472683 = 2147472726
  • 67 + 2147472659 = 2147472726
  • 109 + 2147472617 = 2147472726
  • 227 + 2147472499 = 2147472726
  • 257 + 2147472469 = 2147472726

Showing the first eight; more decompositions exist.
