Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601222, here are decompositions:

13 + 8601209 = 8601222
31 + 8601191 = 8601222
53 + 8601169 = 8601222
59 + 8601163 = 8601222
79 + 8601143 = 8601222
101 + 8601121 = 8601222
109 + 8601113 = 8601222
139 + 8601083 = 8601222

Showing the first eight; more decompositions exist.
