Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147375988, here are decompositions:

  • 19 + 2147375969 = 2147375988
  • 89 + 2147375899 = 2147375988
  • 139 + 2147375849 = 2147375988
  • 181 + 2147375807 = 2147375988
  • 227 + 2147375761 = 2147375988
  • 311 + 2147375677 = 2147375988
  • 347 + 2147375641 = 2147375988
  • 397 + 2147375591 = 2147375988

Showing the first eight; more decompositions exist.
