Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622516, here are decompositions:

7 + 31622509 = 31622516
43 + 31622473 = 31622516
127 + 31622389 = 31622516
139 + 31622377 = 31622516
223 + 31622293 = 31622516
229 + 31622287 = 31622516
337 + 31622179 = 31622516
349 + 31622167 = 31622516

Showing the first eight; more decompositions exist.
