Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622372, here are decompositions:

3 + 31622369 = 31622372
79 + 31622293 = 31622372
193 + 31622179 = 31622372
241 + 31622131 = 31622372
409 + 31621963 = 31622372
541 + 31621831 = 31622372
619 + 31621753 = 31622372
739 + 31621633 = 31622372

Showing the first eight; more decompositions exist.
