Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498928, here are decompositions:

  • 11 + 2147498917 = 2147498928
  • 17 + 2147498911 = 2147498928
  • 97 + 2147498831 = 2147498928
  • 101 + 2147498827 = 2147498928
  • 131 + 2147498797 = 2147498928
  • 191 + 2147498737 = 2147498928
  • 199 + 2147498729 = 2147498928
  • 251 + 2147498677 = 2147498928

Showing the first eight; more decompositions exist.
