Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747328, here are decompositions:

67 + 8747261 = 8747328
71 + 8747257 = 8747328
137 + 8747191 = 8747328
157 + 8747171 = 8747328
257 + 8747071 = 8747328
349 + 8746979 = 8747328
379 + 8746949 = 8747328
389 + 8746939 = 8747328

Showing the first eight; more decompositions exist.
