Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466780, here are decompositions:

  • 59 + 2147466721 = 2147466780
  • 79 + 2147466701 = 2147466780
  • 97 + 2147466683 = 2147466780
  • 101 + 2147466679 = 2147466780
  • 139 + 2147466641 = 2147466780
  • 191 + 2147466589 = 2147466780
  • 233 + 2147466547 = 2147466780
  • 241 + 2147466539 = 2147466780

Showing the first eight; more decompositions exist.
