Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678144, here are decompositions:

3 + 8678141 = 8678144
31 + 8678113 = 8678144
61 + 8678083 = 8678144
151 + 8677993 = 8678144
193 + 8677951 = 8678144
373 + 8677771 = 8678144
421 + 8677723 = 8678144
463 + 8677681 = 8678144

Showing the first eight; more decompositions exist.
