Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147590442, here are decompositions:

  • 13 + 2147590429 = 2147590442
  • 139 + 2147590303 = 2147590442
  • 163 + 2147590279 = 2147590442
  • 181 + 2147590261 = 2147590442
  • 199 + 2147590243 = 2147590442
  • 211 + 2147590231 = 2147590442
  • 223 + 2147590219 = 2147590442
  • 229 + 2147590213 = 2147590442

Showing the first eight; more decompositions exist.
