Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147375976, here are decompositions:

  • 7 + 2147375969 = 2147375976
  • 37 + 2147375939 = 2147375976
  • 107 + 2147375869 = 2147375976
  • 127 + 2147375849 = 2147375976
  • 283 + 2147375693 = 2147375976
  • 293 + 2147375683 = 2147375976
  • 307 + 2147375669 = 2147375976
  • 349 + 2147375627 = 2147375976

Showing the first eight; more decompositions exist.
