Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573704, here are decompositions:

7 + 31573697 = 31573704
61 + 31573643 = 31573704
83 + 31573621 = 31573704
181 + 31573523 = 31573704
191 + 31573513 = 31573704
241 + 31573463 = 31573704
277 + 31573427 = 31573704
311 + 31573393 = 31573704

Showing the first eight; more decompositions exist.
