Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626276, here are decompositions:

29 + 31626247 = 31626276
43 + 31626233 = 31626276
47 + 31626229 = 31626276
67 + 31626209 = 31626276
79 + 31626197 = 31626276
83 + 31626193 = 31626276
109 + 31626167 = 31626276
167 + 31626109 = 31626276

Showing the first eight; more decompositions exist.
