Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467142, here are decompositions:

  • 151 + 2147466991 = 2147467142
  • 199 + 2147466943 = 2147467142
  • 211 + 2147466931 = 2147467142
  • 349 + 2147466793 = 2147467142
  • 421 + 2147466721 = 2147467142
  • 463 + 2147466679 = 2147467142
  • 823 + 2147466319 = 2147467142
  • 829 + 2147466313 = 2147467142

Showing the first eight; more decompositions exist.
