Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573764, here are decompositions:

7 + 31573757 = 31573764
11 + 31573753 = 31573764
17 + 31573747 = 31573764
67 + 31573697 = 31573764
137 + 31573627 = 31573764
181 + 31573583 = 31573764
193 + 31573571 = 31573764
241 + 31573523 = 31573764

Showing the first eight; more decompositions exist.
