Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490430, here are decompositions:

  • 17 + 2147490413 = 2147490430
  • 167 + 2147490263 = 2147490430
  • 191 + 2147490239 = 2147490430
  • 269 + 2147490161 = 2147490430
  • 353 + 2147490077 = 2147490430
  • 419 + 2147490011 = 2147490430
  • 461 + 2147489969 = 2147490430
  • 521 + 2147489909 = 2147490430

Showing the first eight; more decompositions exist.
