Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615250, here are decompositions:

13 + 8615237 = 8615250
19 + 8615231 = 8615250
31 + 8615219 = 8615250
53 + 8615197 = 8615250
73 + 8615177 = 8615250
89 + 8615161 = 8615250
101 + 8615149 = 8615250
113 + 8615137 = 8615250

Showing the first eight; more decompositions exist.
