Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623212, here are decompositions:

19 + 8623193 = 8623212
71 + 8623141 = 8623212
89 + 8623123 = 8623212
109 + 8623103 = 8623212
131 + 8623081 = 8623212
139 + 8623073 = 8623212
151 + 8623061 = 8623212
173 + 8623039 = 8623212

Showing the first eight; more decompositions exist.
