Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473140, here are decompositions:

  • 13 + 2147473127 = 2147473140
  • 19 + 2147473121 = 2147473140
  • 23 + 2147473117 = 2147473140
  • 79 + 2147473061 = 2147473140
  • 181 + 2147472959 = 2147473140
  • 223 + 2147472917 = 2147473140
  • 257 + 2147472883 = 2147473140
  • 277 + 2147472863 = 2147473140

Showing the first eight; more decompositions exist.
