Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573552, here are decompositions:

29 + 31573523 = 31573552
53 + 31573499 = 31573552
89 + 31573463 = 31573552
191 + 31573361 = 31573552
293 + 31573259 = 31573552
389 + 31573163 = 31573552
401 + 31573151 = 31573552
419 + 31573133 = 31573552

Showing the first eight; more decompositions exist.
