Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533586, here are decompositions:

5 + 31533581 = 31533586
23 + 31533563 = 31533586
53 + 31533533 = 31533586
89 + 31533497 = 31533586
137 + 31533449 = 31533586
173 + 31533413 = 31533586
197 + 31533389 = 31533586
317 + 31533269 = 31533586

Showing the first eight; more decompositions exist.
