Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498170, here are decompositions:

  • 23 + 2147498147 = 2147498170
  • 29 + 2147498141 = 2147498170
  • 53 + 2147498117 = 2147498170
  • 137 + 2147498033 = 2147498170
  • 227 + 2147497943 = 2147498170
  • 263 + 2147497907 = 2147498170
  • 269 + 2147497901 = 2147498170
  • 281 + 2147497889 = 2147498170

Showing the first eight; more decompositions exist.
