Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573934, here are decompositions:

3 + 31573931 = 31573934
103 + 31573831 = 31573934
181 + 31573753 = 31573934
307 + 31573627 = 31573934
313 + 31573621 = 31573934
373 + 31573561 = 31573934
421 + 31573513 = 31573934
433 + 31573501 = 31573934

Showing the first eight; more decompositions exist.
