Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601216, here are decompositions:

7 + 8601209 = 8601216
47 + 8601169 = 8601216
53 + 8601163 = 8601216
59 + 8601157 = 8601216
73 + 8601143 = 8601216
103 + 8601113 = 8601216
109 + 8601107 = 8601216
139 + 8601077 = 8601216

Showing the first eight; more decompositions exist.
