Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485970, here are decompositions:

  • 31 + 2147485939 = 2147485970
  • 43 + 2147485927 = 2147485970
  • 73 + 2147485897 = 2147485970
  • 103 + 2147485867 = 2147485970
  • 109 + 2147485861 = 2147485970
  • 127 + 2147485843 = 2147485970
  • 151 + 2147485819 = 2147485970
  • 163 + 2147485807 = 2147485970

Showing the first eight; more decompositions exist.
