Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573834, here are decompositions:

3 + 31573831 = 31573834
11 + 31573823 = 31573834
41 + 31573793 = 31573834
137 + 31573697 = 31573834
191 + 31573643 = 31573834
251 + 31573583 = 31573834
263 + 31573571 = 31573834
311 + 31573523 = 31573834

Showing the first eight; more decompositions exist.
