Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712222, here are decompositions:

41 + 8712181 = 8712222
53 + 8712169 = 8712222
59 + 8712163 = 8712222
73 + 8712149 = 8712222
89 + 8712133 = 8712222
109 + 8712113 = 8712222
131 + 8712091 = 8712222
163 + 8712059 = 8712222

Showing the first eight; more decompositions exist.
