Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573976, here are decompositions:

19 + 31573957 = 31573976
157 + 31573819 = 31573976
223 + 31573753 = 31573976
229 + 31573747 = 31573976
337 + 31573639 = 31573976
349 + 31573627 = 31573976
463 + 31573513 = 31573976
613 + 31573363 = 31573976

Showing the first eight; more decompositions exist.
