Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626386, here are decompositions:

3 + 31626383 = 31626386
19 + 31626367 = 31626386
139 + 31626247 = 31626386
157 + 31626229 = 31626386
193 + 31626193 = 31626386
277 + 31626109 = 31626386
307 + 31626079 = 31626386
313 + 31626073 = 31626386

Showing the first eight; more decompositions exist.
