Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639212, here are decompositions:

5 + 8639207 = 8639212
41 + 8639171 = 8639212
59 + 8639153 = 8639212
89 + 8639123 = 8639212
149 + 8639063 = 8639212
359 + 8638853 = 8639212
479 + 8638733 = 8639212
521 + 8638691 = 8639212

Showing the first eight; more decompositions exist.
