Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574422, here are decompositions:

3 + 31574419 = 31574422
53 + 31574369 = 31574422
59 + 31574363 = 31574422
401 + 31574021 = 31574422
461 + 31573961 = 31574422
491 + 31573931 = 31574422
563 + 31573859 = 31574422
569 + 31573853 = 31574422

Showing the first eight; more decompositions exist.
