Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622632, here are decompositions:

3 + 31622629 = 31622632
53 + 31622579 = 31622632
113 + 31622519 = 31622632
263 + 31622369 = 31622632
359 + 31622273 = 31622632
443 + 31622189 = 31622632
449 + 31622183 = 31622632
479 + 31622153 = 31622632

Showing the first eight; more decompositions exist.
