Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533636, here are decompositions:

5 + 31533631 = 31533636
23 + 31533613 = 31533636
37 + 31533599 = 31533636
73 + 31533563 = 31533636
89 + 31533547 = 31533636
103 + 31533533 = 31533636
137 + 31533499 = 31533636
139 + 31533497 = 31533636

Showing the first eight; more decompositions exist.
