Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573576, here are decompositions:

5 + 31573571 = 31573576
17 + 31573559 = 31573576
53 + 31573523 = 31573576
113 + 31573463 = 31573576
149 + 31573427 = 31573576
317 + 31573259 = 31573576
443 + 31573133 = 31573576
449 + 31573127 = 31573576

Showing the first eight; more decompositions exist.
