Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626270, here are decompositions:

23 + 31626247 = 31626270
37 + 31626233 = 31626270
41 + 31626229 = 31626270
61 + 31626209 = 31626270
73 + 31626197 = 31626270
79 + 31626191 = 31626270
103 + 31626167 = 31626270
139 + 31626131 = 31626270

Showing the first eight; more decompositions exist.
