Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615930, here are decompositions:

13 + 8615917 = 8615930
97 + 8615833 = 8615930
139 + 8615791 = 8615930
163 + 8615767 = 8615930
181 + 8615749 = 8615930
223 + 8615707 = 8615930
277 + 8615653 = 8615930
307 + 8615623 = 8615930

Showing the first eight; more decompositions exist.
