Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678450, here are decompositions:

3 + 8678447 = 8678450
97 + 8678353 = 8678450
127 + 8678323 = 8678450
139 + 8678311 = 8678450
271 + 8678179 = 8678450
337 + 8678113 = 8678450
367 + 8678083 = 8678450
397 + 8678053 = 8678450

Showing the first eight; more decompositions exist.
