Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668212, here are decompositions:

5 + 8668207 = 8668212
11 + 8668201 = 8668212
19 + 8668193 = 8668212
61 + 8668151 = 8668212
71 + 8668141 = 8668212
79 + 8668133 = 8668212
101 + 8668111 = 8668212
131 + 8668081 = 8668212

Showing the first eight; more decompositions exist.
