Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573322, here are decompositions:

43 + 31573279 = 31573322
61 + 31573261 = 31573322
199 + 31573123 = 31573322
211 + 31573111 = 31573322
229 + 31573093 = 31573322
373 + 31572949 = 31573322
379 + 31572943 = 31573322
421 + 31572901 = 31573322

Showing the first eight; more decompositions exist.
