Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627438, here are decompositions:

  • 7 + 8627431 = 8627438
  • 67 + 8627371 = 8627438
  • 97 + 8627341 = 8627438
  • 109 + 8627329 = 8627438
  • 139 + 8627299 = 8627438
  • 181 + 8627257 = 8627438
  • 271 + 8627167 = 8627438
  • 277 + 8627161 = 8627438

Showing the first eight; more decompositions exist.
