Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573684, here are decompositions:

5 + 31573679 = 31573684
41 + 31573643 = 31573684
101 + 31573583 = 31573684
113 + 31573571 = 31573684
257 + 31573427 = 31573684
293 + 31573391 = 31573684
431 + 31573253 = 31573684
521 + 31573163 = 31573684

Showing the first eight; more decompositions exist.
