Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573252, here are decompositions:

41 + 31573211 = 31573252
89 + 31573163 = 31573252
101 + 31573151 = 31573252
149 + 31573103 = 31573252
281 + 31572971 = 31573252
311 + 31572941 = 31573252
383 + 31572869 = 31573252
443 + 31572809 = 31573252

Showing the first eight; more decompositions exist.
