Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662228, here are decompositions:

5 + 8662223 = 8662228
11 + 8662217 = 8662228
41 + 8662187 = 8662228
59 + 8662169 = 8662228
101 + 8662127 = 8662228
137 + 8662091 = 8662228
149 + 8662079 = 8662228
191 + 8662037 = 8662228

Showing the first eight; more decompositions exist.
