Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617478, here are decompositions:

31 + 8617447 = 8617478
61 + 8617417 = 8617478
97 + 8617381 = 8617478
151 + 8617327 = 8617478
241 + 8617237 = 8617478
271 + 8617207 = 8617478
277 + 8617201 = 8617478
307 + 8617171 = 8617478

Showing the first eight; more decompositions exist.
