Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615486, here are decompositions:

7 + 8615479 = 8615486
13 + 8615473 = 8615486
97 + 8615389 = 8615486
109 + 8615377 = 8615486
163 + 8615323 = 8615486
199 + 8615287 = 8615486
337 + 8615149 = 8615486
349 + 8615137 = 8615486

Showing the first eight; more decompositions exist.
