Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573588, here are decompositions:

5 + 31573583 = 31573588
17 + 31573571 = 31573588
29 + 31573559 = 31573588
89 + 31573499 = 31573588
197 + 31573391 = 31573588
227 + 31573361 = 31573588
311 + 31573277 = 31573588
461 + 31573127 = 31573588

Showing the first eight; more decompositions exist.
