Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729396, here are decompositions:

7 + 8729389 = 8729396
73 + 8729323 = 8729396
79 + 8729317 = 8729396
157 + 8729239 = 8729396
223 + 8729173 = 8729396
337 + 8729059 = 8729396
409 + 8728987 = 8729396
433 + 8728963 = 8729396

Showing the first eight; more decompositions exist.
