Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626546, here are decompositions:

13 + 31626533 = 31626546
47 + 31626499 = 31626546
53 + 31626493 = 31626546
109 + 31626437 = 31626546
139 + 31626407 = 31626546
157 + 31626389 = 31626546
163 + 31626383 = 31626546
179 + 31626367 = 31626546

Showing the first eight; more decompositions exist.
