Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626586, here are decompositions:

23 + 31626563 = 31626586
29 + 31626557 = 31626586
53 + 31626533 = 31626586
149 + 31626437 = 31626586
179 + 31626407 = 31626586
197 + 31626389 = 31626586
227 + 31626359 = 31626586
263 + 31626323 = 31626586

Showing the first eight; more decompositions exist.
