Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530622, here are decompositions:

  • 5 + 31530617 = 31530622
  • 29 + 31530593 = 31530622
  • 239 + 31530383 = 31530622
  • 281 + 31530341 = 31530622
  • 311 + 31530311 = 31530622
  • 353 + 31530269 = 31530622
  • 419 + 31530203 = 31530622
  • 449 + 31530173 = 31530622

Showing the first eight; more decompositions exist.
