Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615394, here are decompositions:

5 + 8615389 = 8615394
17 + 8615377 = 8615394
61 + 8615333 = 8615394
71 + 8615323 = 8615394
107 + 8615287 = 8615394
127 + 8615267 = 8615394
157 + 8615237 = 8615394
163 + 8615231 = 8615394

Showing the first eight; more decompositions exist.
