Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147375868, here are decompositions:

  • 19 + 2147375849 = 2147375868
  • 61 + 2147375807 = 2147375868
  • 107 + 2147375761 = 2147375868
  • 139 + 2147375729 = 2147375868
  • 191 + 2147375677 = 2147375868
  • 199 + 2147375669 = 2147375868
  • 227 + 2147375641 = 2147375868
  • 241 + 2147375627 = 2147375868

Showing the first eight; more decompositions exist.
