Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729144, here are decompositions:

3 + 8729141 = 8729144
13 + 8729131 = 8729144
37 + 8729107 = 8729144
157 + 8728987 = 8729144
181 + 8728963 = 8729144
223 + 8728921 = 8729144
241 + 8728903 = 8729144
337 + 8728807 = 8729144

Showing the first eight; more decompositions exist.
