Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622948, here are decompositions:

67 + 31622881 = 31622948
139 + 31622809 = 31622948
277 + 31622671 = 31622948
307 + 31622641 = 31622948
349 + 31622599 = 31622948
439 + 31622509 = 31622948
457 + 31622491 = 31622948
571 + 31622377 = 31622948

Showing the first eight; more decompositions exist.
