Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468930, here are decompositions:

  • 7 + 2147468923 = 2147468930
  • 43 + 2147468887 = 2147468930
  • 97 + 2147468833 = 2147468930
  • 127 + 2147468803 = 2147468930
  • 151 + 2147468779 = 2147468930
  • 157 + 2147468773 = 2147468930
  • 331 + 2147468599 = 2147468930
  • 367 + 2147468563 = 2147468930

Showing the first eight; more decompositions exist.
