Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690672, here are decompositions:

13 + 8690659 = 8690672
61 + 8690611 = 8690672
73 + 8690599 = 8690672
79 + 8690593 = 8690672
313 + 8690359 = 8690672
379 + 8690293 = 8690672
499 + 8690173 = 8690672
631 + 8690041 = 8690672

Showing the first eight; more decompositions exist.
