Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147496990, here are decompositions:

  • 11 + 2147496979 = 2147496990
  • 19 + 2147496971 = 2147496990
  • 29 + 2147496961 = 2147496990
  • 53 + 2147496937 = 2147496990
  • 73 + 2147496917 = 2147496990
  • 127 + 2147496863 = 2147496990
  • 131 + 2147496859 = 2147496990
  • 137 + 2147496853 = 2147496990

Showing the first eight; more decompositions exist.
