Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626382, here are decompositions:

5 + 31626377 = 31626382
23 + 31626359 = 31626382
59 + 31626323 = 31626382
149 + 31626233 = 31626382
173 + 31626209 = 31626382
191 + 31626191 = 31626382
251 + 31626131 = 31626382
401 + 31625981 = 31626382

Showing the first eight; more decompositions exist.
