Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573848, here are decompositions:

17 + 31573831 = 31573848
29 + 31573819 = 31573848
101 + 31573747 = 31573848
151 + 31573697 = 31573848
227 + 31573621 = 31573848
277 + 31573571 = 31573848
347 + 31573501 = 31573848
349 + 31573499 = 31573848

Showing the first eight; more decompositions exist.
