Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473158, here are decompositions:

  • 7 + 2147473151 = 2147473158
  • 31 + 2147473127 = 2147473158
  • 37 + 2147473121 = 2147473158
  • 41 + 2147473117 = 2147473158
  • 97 + 2147473061 = 2147473158
  • 109 + 2147473049 = 2147473158
  • 199 + 2147472959 = 2147473158
  • 241 + 2147472917 = 2147473158

Showing the first eight; more decompositions exist.
