Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622750, here are decompositions:

7 + 31622743 = 31622750
37 + 31622713 = 31622750
67 + 31622683 = 31622750
79 + 31622671 = 31622750
109 + 31622641 = 31622750
151 + 31622599 = 31622750
241 + 31622509 = 31622750
277 + 31622473 = 31622750

Showing the first eight; more decompositions exist.
