Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622852, here are decompositions:

43 + 31622809 = 31622852
73 + 31622779 = 31622852
109 + 31622743 = 31622852
139 + 31622713 = 31622852
181 + 31622671 = 31622852
211 + 31622641 = 31622852
223 + 31622629 = 31622852
379 + 31622473 = 31622852

Showing the first eight; more decompositions exist.
