Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622756, here are decompositions:

13 + 31622743 = 31622756
43 + 31622713 = 31622756
73 + 31622683 = 31622756
127 + 31622629 = 31622756
157 + 31622599 = 31622756
283 + 31622473 = 31622756
367 + 31622389 = 31622756
379 + 31622377 = 31622756

Showing the first eight; more decompositions exist.
