Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573364, here are decompositions:

3 + 31573361 = 31573364
7 + 31573357 = 31573364
103 + 31573261 = 31573364
211 + 31573153 = 31573364
241 + 31573123 = 31573364
271 + 31573093 = 31573364
307 + 31573057 = 31573364
337 + 31573027 = 31573364

Showing the first eight; more decompositions exist.
