Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573606, here are decompositions:

23 + 31573583 = 31573606
47 + 31573559 = 31573606
83 + 31573523 = 31573606
107 + 31573499 = 31573606
179 + 31573427 = 31573606
347 + 31573259 = 31573606
353 + 31573253 = 31573606
443 + 31573163 = 31573606

Showing the first eight; more decompositions exist.
