Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533684, here are decompositions:

23 + 31533661 = 31533684
43 + 31533641 = 31533684
47 + 31533637 = 31533684
53 + 31533631 = 31533684
71 + 31533613 = 31533684
73 + 31533611 = 31533684
97 + 31533587 = 31533684
103 + 31533581 = 31533684

Showing the first eight; more decompositions exist.
