Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573914, here are decompositions:

61 + 31573853 = 31573914
67 + 31573847 = 31573914
83 + 31573831 = 31573914
157 + 31573757 = 31573914
167 + 31573747 = 31573914
271 + 31573643 = 31573914
293 + 31573621 = 31573914
331 + 31573583 = 31573914

Showing the first eight; more decompositions exist.
