Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745626, here are decompositions:

13 + 8745613 = 8745626
73 + 8745553 = 8745626
79 + 8745547 = 8745626
103 + 8745523 = 8745626
283 + 8745343 = 8745626
457 + 8745169 = 8745626
607 + 8745019 = 8745626
709 + 8744917 = 8745626

Showing the first eight; more decompositions exist.
