Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573732, here are decompositions:

53 + 31573679 = 31573732
89 + 31573643 = 31573732
149 + 31573583 = 31573732
173 + 31573559 = 31573732
233 + 31573499 = 31573732
269 + 31573463 = 31573732
479 + 31573253 = 31573732
521 + 31573211 = 31573732

Showing the first eight; more decompositions exist.
