Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573636, here are decompositions:

53 + 31573583 = 31573636
113 + 31573523 = 31573636
137 + 31573499 = 31573636
173 + 31573463 = 31573636
359 + 31573277 = 31573636
383 + 31573253 = 31573636
503 + 31573133 = 31573636
509 + 31573127 = 31573636

Showing the first eight; more decompositions exist.
