Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626832, here are decompositions:

5 + 31626827 = 31626832
269 + 31626563 = 31626832
443 + 31626389 = 31626832
449 + 31626383 = 31626832
509 + 31626323 = 31626832
599 + 31626233 = 31626832
641 + 31626191 = 31626832
701 + 31626131 = 31626832

Showing the first eight; more decompositions exist.
