Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622530, here are decompositions:

11 + 31622519 = 31622530
101 + 31622429 = 31622530
257 + 31622273 = 31622530
293 + 31622237 = 31622530
347 + 31622183 = 31622530
383 + 31622147 = 31622530
389 + 31622141 = 31622530
449 + 31622081 = 31622530

Showing the first eight; more decompositions exist.
