Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620210, here are decompositions:

  • 23 + 8620187 = 8620210
  • 59 + 8620151 = 8620210
  • 89 + 8620121 = 8620210
  • 101 + 8620109 = 8620210
  • 167 + 8620043 = 8620210
  • 317 + 8619893 = 8620210
  • 353 + 8619857 = 8620210
  • 419 + 8619791 = 8620210

Showing the first eight; more decompositions exist.
