Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573832, here are decompositions:

13 + 31573819 = 31573832
79 + 31573753 = 31573832
193 + 31573639 = 31573832
211 + 31573621 = 31573832
271 + 31573561 = 31573832
331 + 31573501 = 31573832
439 + 31573393 = 31573832
571 + 31573261 = 31573832

Showing the first eight; more decompositions exist.
