Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573696, here are decompositions:

17 + 31573679 = 31573696
53 + 31573643 = 31573696
113 + 31573583 = 31573696
137 + 31573559 = 31573696
173 + 31573523 = 31573696
197 + 31573499 = 31573696
233 + 31573463 = 31573696
269 + 31573427 = 31573696

Showing the first eight; more decompositions exist.
