Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687210, here are decompositions:

3 + 8687207 = 8687210
13 + 8687197 = 8687210
61 + 8687149 = 8687210
79 + 8687131 = 8687210
211 + 8686999 = 8687210
229 + 8686981 = 8687210
523 + 8686687 = 8687210
541 + 8686669 = 8687210

Showing the first eight; more decompositions exist.
