Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678242, here are decompositions:

5 + 8678237 = 8678242
29 + 8678213 = 8678242
101 + 8678141 = 8678242
113 + 8678129 = 8678242
149 + 8678093 = 8678242
173 + 8678069 = 8678242
179 + 8678063 = 8678242
191 + 8678051 = 8678242

Showing the first eight; more decompositions exist.
