Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729360, here are decompositions:

37 + 8729323 = 8729360
43 + 8729317 = 8729360
139 + 8729221 = 8729360
181 + 8729179 = 8729360
229 + 8729131 = 8729360
307 + 8729053 = 8729360
373 + 8728987 = 8729360
397 + 8728963 = 8729360

Showing the first eight; more decompositions exist.
