Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622552, here are decompositions:

43 + 31622509 = 31622552
61 + 31622491 = 31622552
79 + 31622473 = 31622552
163 + 31622389 = 31622552
271 + 31622281 = 31622552
373 + 31622179 = 31622552
421 + 31622131 = 31622552
433 + 31622119 = 31622552

Showing the first eight; more decompositions exist.
