Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622534, here are decompositions:

43 + 31622491 = 31622534
61 + 31622473 = 31622534
67 + 31622467 = 31622534
157 + 31622377 = 31622534
241 + 31622293 = 31622534
277 + 31622257 = 31622534
367 + 31622167 = 31622534
421 + 31622113 = 31622534

Showing the first eight; more decompositions exist.
