Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626562, here are decompositions:

5 + 31626557 = 31626562
29 + 31626533 = 31626562
101 + 31626461 = 31626562
173 + 31626389 = 31626562
179 + 31626383 = 31626562
239 + 31626323 = 31626562
353 + 31626209 = 31626562
431 + 31626131 = 31626562

Showing the first eight; more decompositions exist.
