Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472786, here are decompositions:

  • 29 + 2147472757 = 2147472786
  • 73 + 2147472713 = 2147472786
  • 89 + 2147472697 = 2147472786
  • 97 + 2147472689 = 2147472786
  • 103 + 2147472683 = 2147472786
  • 127 + 2147472659 = 2147472786
  • 229 + 2147472557 = 2147472786
  • 317 + 2147472469 = 2147472786

Showing the first eight; more decompositions exist.
