Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573964, here are decompositions:

3 + 31573961 = 31573964
7 + 31573957 = 31573964
211 + 31573753 = 31573964
337 + 31573627 = 31573964
463 + 31573501 = 31573964
571 + 31573393 = 31573964
601 + 31573363 = 31573964
607 + 31573357 = 31573964

Showing the first eight; more decompositions exist.
