Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620212, here are decompositions:

23 + 8620189 = 8620212
53 + 8620159 = 8620212
61 + 8620151 = 8620212
71 + 8620141 = 8620212
79 + 8620133 = 8620212
101 + 8620111 = 8620212
103 + 8620109 = 8620212
149 + 8620063 = 8620212

Showing the first eight; more decompositions exist.
