Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573710, here are decompositions:

13 + 31573697 = 31573710
31 + 31573679 = 31573710
67 + 31573643 = 31573710
71 + 31573639 = 31573710
83 + 31573627 = 31573710
89 + 31573621 = 31573710
127 + 31573583 = 31573710
139 + 31573571 = 31573710

Showing the first eight; more decompositions exist.
