Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748678, here are decompositions:

5 + 8748673 = 8748678
31 + 8748647 = 8748678
79 + 8748599 = 8748678
89 + 8748589 = 8748678
97 + 8748581 = 8748678
179 + 8748499 = 8748678
311 + 8748367 = 8748678
317 + 8748361 = 8748678

Showing the first eight; more decompositions exist.
