Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573692, here are decompositions:

13 + 31573679 = 31573692
53 + 31573639 = 31573692
71 + 31573621 = 31573692
109 + 31573583 = 31573692
131 + 31573561 = 31573692
179 + 31573513 = 31573692
191 + 31573501 = 31573692
193 + 31573499 = 31573692

Showing the first eight; more decompositions exist.
