Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622012, here are decompositions:

31 + 31621981 = 31622012
181 + 31621831 = 31622012
379 + 31621633 = 31622012
421 + 31621591 = 31622012
571 + 31621441 = 31622012
613 + 31621399 = 31622012
619 + 31621393 = 31622012
1039 + 31620973 = 31622012

Showing the first eight; more decompositions exist.
