Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622574, here are decompositions:

37 + 31622537 = 31622574
83 + 31622491 = 31622574
101 + 31622473 = 31622574
107 + 31622467 = 31622574
197 + 31622377 = 31622574
227 + 31622347 = 31622574
281 + 31622293 = 31622574
293 + 31622281 = 31622574

Showing the first eight; more decompositions exist.
