Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489980, here are decompositions:

  • 11 + 2147489969 = 2147489980
  • 23 + 2147489957 = 2147489980
  • 71 + 2147489909 = 2147489980
  • 107 + 2147489873 = 2147489980
  • 131 + 2147489849 = 2147489980
  • 137 + 2147489843 = 2147489980
  • 263 + 2147489717 = 2147489980
  • 281 + 2147489699 = 2147489980

Showing the first eight; more decompositions exist.
