Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626652, here are decompositions:

89 + 31626563 = 31626652
191 + 31626461 = 31626652
263 + 31626389 = 31626652
269 + 31626383 = 31626652
293 + 31626359 = 31626652
419 + 31626233 = 31626652
443 + 31626209 = 31626652
461 + 31626191 = 31626652

Showing the first eight; more decompositions exist.
