Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615526, here are decompositions:

13 + 8615513 = 8615526
19 + 8615507 = 8615526
47 + 8615479 = 8615526
53 + 8615473 = 8615526
103 + 8615423 = 8615526
137 + 8615389 = 8615526
149 + 8615377 = 8615526
193 + 8615333 = 8615526

Showing the first eight; more decompositions exist.
