Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468122, here are decompositions:

  • 3 + 2147468119 = 2147468122
  • 53 + 2147468069 = 2147468122
  • 251 + 2147467871 = 2147468122
  • 353 + 2147467769 = 2147468122
  • 389 + 2147467733 = 2147468122
  • 491 + 2147467631 = 2147468122
  • 563 + 2147467559 = 2147468122
  • 659 + 2147467463 = 2147468122

Showing the first eight; more decompositions exist.
