Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626436, here are decompositions:

29 + 31626407 = 31626436
47 + 31626389 = 31626436
53 + 31626383 = 31626436
59 + 31626377 = 31626436
113 + 31626323 = 31626436
227 + 31626209 = 31626436
239 + 31626197 = 31626436
269 + 31626167 = 31626436

Showing the first eight; more decompositions exist.
