Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618274, here are decompositions:

17 + 8618257 = 8618274
23 + 8618251 = 8618274
31 + 8618243 = 8618274
37 + 8618237 = 8618274
53 + 8618221 = 8618274
61 + 8618213 = 8618274
101 + 8618173 = 8618274
127 + 8618147 = 8618274

Showing the first eight; more decompositions exist.
