Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622566, here are decompositions:

29 + 31622537 = 31622566
47 + 31622519 = 31622566
137 + 31622429 = 31622566
197 + 31622369 = 31622566
293 + 31622273 = 31622566
359 + 31622207 = 31622566
383 + 31622183 = 31622566
419 + 31622147 = 31622566

Showing the first eight; more decompositions exist.
