Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678272, here are decompositions:

59 + 8678213 = 8678272
131 + 8678141 = 8678272
179 + 8678093 = 8678272
191 + 8678081 = 8678272
233 + 8678039 = 8678272
293 + 8677979 = 8678272
311 + 8677961 = 8678272
389 + 8677883 = 8678272

Showing the first eight; more decompositions exist.
