Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582622, here are decompositions:

13 + 31582609 = 31582622
109 + 31582513 = 31582622
151 + 31582471 = 31582622
223 + 31582399 = 31582622
373 + 31582249 = 31582622
439 + 31582183 = 31582622
601 + 31582021 = 31582622
619 + 31582003 = 31582622

Showing the first eight; more decompositions exist.
