Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622672, here are decompositions:

31 + 31622641 = 31622672
43 + 31622629 = 31622672
73 + 31622599 = 31622672
163 + 31622509 = 31622672
181 + 31622491 = 31622672
199 + 31622473 = 31622672
283 + 31622389 = 31622672
379 + 31622293 = 31622672

Showing the first eight; more decompositions exist.
