Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615918, here are decompositions:

37 + 8615881 = 8615918
109 + 8615809 = 8615918
127 + 8615791 = 8615918
151 + 8615767 = 8615918
211 + 8615707 = 8615918
331 + 8615587 = 8615918
379 + 8615539 = 8615918
439 + 8615479 = 8615918

Showing the first eight; more decompositions exist.
