Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729378, here are decompositions:

61 + 8729317 = 8729378
139 + 8729239 = 8729378
157 + 8729221 = 8729378
199 + 8729179 = 8729378
271 + 8729107 = 8729378
409 + 8728969 = 8729378
457 + 8728921 = 8729378
571 + 8728807 = 8729378

Showing the first eight; more decompositions exist.
