Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617212, here are decompositions:

5 + 8617207 = 8617212
11 + 8617201 = 8617212
41 + 8617171 = 8617212
59 + 8617153 = 8617212
83 + 8617129 = 8617212
103 + 8617109 = 8617212
139 + 8617073 = 8617212
211 + 8617001 = 8617212

Showing the first eight; more decompositions exist.
