Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573076, here are decompositions:

19 + 31573057 = 31573076
97 + 31572979 = 31573076
127 + 31572949 = 31573076
307 + 31572769 = 31573076
313 + 31572763 = 31573076
349 + 31572727 = 31573076
439 + 31572637 = 31573076
487 + 31572589 = 31573076

Showing the first eight; more decompositions exist.
