Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147477100, here are decompositions:

  • 7 + 2147477093 = 2147477100
  • 37 + 2147477063 = 2147477100
  • 71 + 2147477029 = 2147477100
  • 79 + 2147477021 = 2147477100
  • 137 + 2147476963 = 2147477100
  • 149 + 2147476951 = 2147477100
  • 157 + 2147476943 = 2147477100
  • 163 + 2147476937 = 2147477100

Showing the first eight; more decompositions exist.
