Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678480, here are decompositions:

7 + 8678473 = 8678480
127 + 8678353 = 8678480
157 + 8678323 = 8678480
277 + 8678203 = 8678480
331 + 8678149 = 8678480
367 + 8678113 = 8678480
397 + 8678083 = 8678480
487 + 8677993 = 8678480

Showing the first eight; more decompositions exist.
