Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622056, here are decompositions:

107 + 31621949 = 31622056
317 + 31621739 = 31622056
353 + 31621703 = 31622056
383 + 31621673 = 31622056
419 + 31621637 = 31622056
443 + 31621613 = 31622056
569 + 31621487 = 31622056
797 + 31621259 = 31622056

Showing the first eight; more decompositions exist.
