Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147377980, here are decompositions:

  • 19 + 2147377961 = 2147377980
  • 29 + 2147377951 = 2147377980
  • 37 + 2147377943 = 2147377980
  • 53 + 2147377927 = 2147377980
  • 101 + 2147377879 = 2147377980
  • 109 + 2147377871 = 2147377980
  • 191 + 2147377789 = 2147377980
  • 193 + 2147377787 = 2147377980

Showing the first eight; more decompositions exist.
