Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147399160, here are decompositions:

  • 7 + 2147399153 = 2147399160
  • 13 + 2147399147 = 2147399160
  • 19 + 2147399141 = 2147399160
  • 37 + 2147399123 = 2147399160
  • 47 + 2147399113 = 2147399160
  • 73 + 2147399087 = 2147399160
  • 97 + 2147399063 = 2147399160
  • 107 + 2147399053 = 2147399160

Showing the first eight; more decompositions exist.
