Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622542, here are decompositions:

5 + 31622537 = 31622542
23 + 31622519 = 31622542
113 + 31622429 = 31622542
173 + 31622369 = 31622542
269 + 31622273 = 31622542
353 + 31622189 = 31622542
359 + 31622183 = 31622542
389 + 31622153 = 31622542

Showing the first eight; more decompositions exist.
