Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147585834, here are decompositions:

  • 67 + 2147585767 = 2147585834
  • 103 + 2147585731 = 2147585834
  • 151 + 2147585683 = 2147585834
  • 157 + 2147585677 = 2147585834
  • 181 + 2147585653 = 2147585834
  • 211 + 2147585623 = 2147585834
  • 223 + 2147585611 = 2147585834
  • 271 + 2147585563 = 2147585834

Showing the first eight; more decompositions exist.
