Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147588940, here are decompositions:

  • 31 + 2147588909 = 2147588940
  • 53 + 2147588887 = 2147588940
  • 61 + 2147588879 = 2147588940
  • 67 + 2147588873 = 2147588940
  • 83 + 2147588857 = 2147588940
  • 137 + 2147588803 = 2147588940
  • 281 + 2147588659 = 2147588940
  • 283 + 2147588657 = 2147588940

Showing the first eight; more decompositions exist.
