Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622442, here are decompositions:

13 + 31622429 = 31622442
53 + 31622389 = 31622442
73 + 31622369 = 31622442
149 + 31622293 = 31622442
263 + 31622179 = 31622442
311 + 31622131 = 31622442
461 + 31621981 = 31622442
463 + 31621979 = 31622442

Showing the first eight; more decompositions exist.
