Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618456, here are decompositions:

13 + 8618443 = 8618456
43 + 8618413 = 8618456
79 + 8618377 = 8618456
127 + 8618329 = 8618456
139 + 8618317 = 8618456
163 + 8618293 = 8618456
199 + 8618257 = 8618456
283 + 8618173 = 8618456

Showing the first eight; more decompositions exist.
