Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467688, here are decompositions:

  • 19 + 2147467669 = 2147467688
  • 61 + 2147467627 = 2147467688
  • 109 + 2147467579 = 2147467688
  • 349 + 2147467339 = 2147467688
  • 367 + 2147467321 = 2147467688
  • 631 + 2147467057 = 2147467688
  • 757 + 2147466931 = 2147467688
  • 967 + 2147466721 = 2147467688

Showing the first eight; more decompositions exist.
