Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147480846, here are decompositions:

  • 3 + 2147480843 = 2147480846
  • 103 + 2147480743 = 2147480846
  • 139 + 2147480707 = 2147480846
  • 163 + 2147480683 = 2147480846
  • 223 + 2147480623 = 2147480846
  • 409 + 2147480437 = 2147480846
  • 547 + 2147480299 = 2147480846
  • 619 + 2147480227 = 2147480846

Showing the first eight; more decompositions exist.
