Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688470, here are decompositions:

61 + 8688409 = 8688470
73 + 8688397 = 8688470
199 + 8688271 = 8688470
211 + 8688259 = 8688470
313 + 8688157 = 8688470
337 + 8688133 = 8688470
457 + 8688013 = 8688470
487 + 8687983 = 8688470

Showing the first eight; more decompositions exist.
