Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729426, here are decompositions:

37 + 8729389 = 8729426
103 + 8729323 = 8729426
109 + 8729317 = 8729426
367 + 8729059 = 8729426
373 + 8729053 = 8729426
439 + 8728987 = 8729426
457 + 8728969 = 8729426
463 + 8728963 = 8729426

Showing the first eight; more decompositions exist.
