Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573634, here are decompositions:

7 + 31573627 = 31573634
13 + 31573621 = 31573634
73 + 31573561 = 31573634
241 + 31573393 = 31573634
271 + 31573363 = 31573634
277 + 31573357 = 31573634
373 + 31573261 = 31573634
523 + 31573111 = 31573634

Showing the first eight; more decompositions exist.
