Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147392260, here are decompositions:

  • 7 + 2147392253 = 2147392260
  • 11 + 2147392249 = 2147392260
  • 17 + 2147392243 = 2147392260
  • 59 + 2147392201 = 2147392260
  • 71 + 2147392189 = 2147392260
  • 107 + 2147392153 = 2147392260
  • 109 + 2147392151 = 2147392260
  • 113 + 2147392147 = 2147392260

Showing the first eight; more decompositions exist.
