Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622506, here are decompositions:

137 + 31622369 = 31622506
233 + 31622273 = 31622506
269 + 31622237 = 31622506
317 + 31622189 = 31622506
353 + 31622153 = 31622506
359 + 31622147 = 31622506
557 + 31621949 = 31622506
659 + 31621847 = 31622506

Showing the first eight; more decompositions exist.
