Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624678, here are decompositions:

61 + 8624617 = 8624678
79 + 8624599 = 8624678
229 + 8624449 = 8624678
367 + 8624311 = 8624678
457 + 8624221 = 8624678
487 + 8624191 = 8624678
499 + 8624179 = 8624678
541 + 8624137 = 8624678

Showing the first eight; more decompositions exist.
