Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615480, here are decompositions:

7 + 8615473 = 8615480
19 + 8615461 = 8615480
103 + 8615377 = 8615480
157 + 8615323 = 8615480
193 + 8615287 = 8615480
283 + 8615197 = 8615480
331 + 8615149 = 8615480
397 + 8615083 = 8615480

Showing the first eight; more decompositions exist.
