Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533642, here are decompositions:

5 + 31533637 = 31533642
11 + 31533631 = 31533642
29 + 31533613 = 31533642
31 + 31533611 = 31533642
43 + 31533599 = 31533642
61 + 31533581 = 31533642
71 + 31533571 = 31533642
79 + 31533563 = 31533642

Showing the first eight; more decompositions exist.
