Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662278, here are decompositions:

5 + 8662273 = 8662278
19 + 8662259 = 8662278
29 + 8662249 = 8662278
59 + 8662219 = 8662278
61 + 8662217 = 8662278
89 + 8662189 = 8662278
101 + 8662177 = 8662278
109 + 8662169 = 8662278

Showing the first eight; more decompositions exist.
