Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687354, here are decompositions:

37 + 8687317 = 8687354
127 + 8687227 = 8687354
157 + 8687197 = 8687354
223 + 8687131 = 8687354
373 + 8686981 = 8687354
547 + 8686807 = 8687354
787 + 8686567 = 8687354
853 + 8686501 = 8687354

Showing the first eight; more decompositions exist.
