Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469954, here are decompositions:

  • 5 + 2147469949 = 2147469954
  • 11 + 2147469943 = 2147469954
  • 37 + 2147469917 = 2147469954
  • 73 + 2147469881 = 2147469954
  • 131 + 2147469823 = 2147469954
  • 137 + 2147469817 = 2147469954
  • 173 + 2147469781 = 2147469954
  • 251 + 2147469703 = 2147469954

Showing the first eight; more decompositions exist.
