Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662478, here are decompositions:

7 + 8662471 = 8662478
31 + 8662447 = 8662478
37 + 8662441 = 8662478
67 + 8662411 = 8662478
151 + 8662327 = 8662478
199 + 8662279 = 8662478
229 + 8662249 = 8662478
277 + 8662201 = 8662478

Showing the first eight; more decompositions exist.
