Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573464, here are decompositions:

37 + 31573427 = 31573464
71 + 31573393 = 31573464
73 + 31573391 = 31573464
101 + 31573363 = 31573464
103 + 31573361 = 31573464
107 + 31573357 = 31573464
211 + 31573253 = 31573464
311 + 31573153 = 31573464

Showing the first eight; more decompositions exist.
