Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678284, here are decompositions:

47 + 8678237 = 8678284
71 + 8678213 = 8678284
137 + 8678147 = 8678284
191 + 8678093 = 8678284
227 + 8678057 = 8678284
233 + 8678051 = 8678284
257 + 8678027 = 8678284
317 + 8677967 = 8678284

Showing the first eight; more decompositions exist.
