Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467756, here are decompositions:

  • 23 + 2147467733 = 2147467756
  • 59 + 2147467697 = 2147467756
  • 89 + 2147467667 = 2147467756
  • 173 + 2147467583 = 2147467756
  • 197 + 2147467559 = 2147467756
  • 263 + 2147467493 = 2147467756
  • 293 + 2147467463 = 2147467756
  • 353 + 2147467403 = 2147467756

Showing the first eight; more decompositions exist.
