Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573804, here are decompositions:

11 + 31573793 = 31573804
47 + 31573757 = 31573804
107 + 31573697 = 31573804
233 + 31573571 = 31573804
281 + 31573523 = 31573804
443 + 31573361 = 31573804
593 + 31573211 = 31573804
641 + 31573163 = 31573804

Showing the first eight; more decompositions exist.
