Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662172, here are decompositions:

3 + 8662169 = 8662172
19 + 8662153 = 8662172
151 + 8662021 = 8662172
163 + 8662009 = 8662172
229 + 8661943 = 8662172
271 + 8661901 = 8662172
283 + 8661889 = 8662172
331 + 8661841 = 8662172

Showing the first eight; more decompositions exist.
