Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627408, here are decompositions:

  • 37 + 8627371 = 8627408
  • 67 + 8627341 = 8627408
  • 79 + 8627329 = 8627408
  • 109 + 8627299 = 8627408
  • 151 + 8627257 = 8627408
  • 157 + 8627251 = 8627408
  • 241 + 8627167 = 8627408
  • 379 + 8627029 = 8627408

Showing the first eight; more decompositions exist.
