Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626102, here are decompositions:

23 + 31626079 = 31626102
29 + 31626073 = 31626102
61 + 31626041 = 31626102
83 + 31626019 = 31626102
139 + 31625963 = 31626102
149 + 31625953 = 31626102
163 + 31625939 = 31626102
191 + 31625911 = 31626102

Showing the first eight; more decompositions exist.
