Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662212, here are decompositions:

11 + 8662201 = 8662212
23 + 8662189 = 8662212
43 + 8662169 = 8662212
59 + 8662153 = 8662212
61 + 8662151 = 8662212
79 + 8662133 = 8662212
103 + 8662109 = 8662212
191 + 8662021 = 8662212

Showing the first eight; more decompositions exist.
