Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622456, here are decompositions:

67 + 31622389 = 31622456
79 + 31622377 = 31622456
109 + 31622347 = 31622456
163 + 31622293 = 31622456
199 + 31622257 = 31622456
277 + 31622179 = 31622456
337 + 31622119 = 31622456
409 + 31622047 = 31622456

Showing the first eight; more decompositions exist.
