Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622418, here are decompositions:

  • 29 + 31622389 = 31622418
  • 41 + 31622377 = 31622418
  • 71 + 31622347 = 31622418
  • 131 + 31622287 = 31622418
  • 137 + 31622281 = 31622418
  • 181 + 31622237 = 31622418
  • 211 + 31622207 = 31622418
  • 229 + 31622189 = 31622418

Showing the first eight; more decompositions exist.
