Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615340, here are decompositions:

7 + 8615333 = 8615340
17 + 8615323 = 8615340
53 + 8615287 = 8615340
61 + 8615279 = 8615340
67 + 8615273 = 8615340
73 + 8615267 = 8615340
79 + 8615261 = 8615340
103 + 8615237 = 8615340

Showing the first eight; more decompositions exist.
