Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678532, here are decompositions:

13 + 8678519 = 8678532
59 + 8678473 = 8678532
139 + 8678393 = 8678532
173 + 8678359 = 8678532
179 + 8678353 = 8678532
193 + 8678339 = 8678532
199 + 8678333 = 8678532
353 + 8678179 = 8678532

Showing the first eight; more decompositions exist.
