Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467646, here are decompositions:

  • 7 + 2147467639 = 2147467646
  • 19 + 2147467627 = 2147467646
  • 67 + 2147467579 = 2147467646
  • 307 + 2147467339 = 2147467646
  • 673 + 2147466973 = 2147467646
  • 853 + 2147466793 = 2147467646
  • 859 + 2147466787 = 2147467646
  • 967 + 2147466679 = 2147467646

Showing the first eight; more decompositions exist.
