Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626844, here are decompositions:

3 + 31626841 = 31626844
5 + 31626839 = 31626844
17 + 31626827 = 31626844
47 + 31626797 = 31626844
281 + 31626563 = 31626844
311 + 31626533 = 31626844
383 + 31626461 = 31626844
461 + 31626383 = 31626844

Showing the first eight; more decompositions exist.
