Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620518, here are decompositions:

  • 19 + 8620499 = 8620518
  • 89 + 8620429 = 8620518
  • 149 + 8620369 = 8620518
  • 157 + 8620361 = 8620518
  • 191 + 8620327 = 8620518
  • 211 + 8620307 = 8620518
  • 229 + 8620289 = 8620518
  • 241 + 8620277 = 8620518

Showing the first eight; more decompositions exist.
