Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538422, here are decompositions:

11 + 31538411 = 31538422
89 + 31538333 = 31538422
269 + 31538153 = 31538422
281 + 31538141 = 31538422
359 + 31538063 = 31538422
389 + 31538033 = 31538422
563 + 31537859 = 31538422
599 + 31537823 = 31538422

Showing the first eight; more decompositions exist.
