Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468366, here are decompositions:

  • 97 + 2147468269 = 2147468366
  • 193 + 2147468173 = 2147468366
  • 607 + 2147467759 = 2147468366
  • 619 + 2147467747 = 2147468366
  • 727 + 2147467639 = 2147468366
  • 739 + 2147467627 = 2147468366
  • 787 + 2147467579 = 2147468366
  • 1039 + 2147467327 = 2147468366

Showing the first eight; more decompositions exist.
