Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737228, here are decompositions:

29 + 8737199 = 8737228
89 + 8737139 = 8737228
131 + 8737097 = 8737228
167 + 8737061 = 8737228
179 + 8737049 = 8737228
239 + 8736989 = 8737228
317 + 8736911 = 8737228
347 + 8736881 = 8737228

Showing the first eight; more decompositions exist.
