Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573348, here are decompositions:

71 + 31573277 = 31573348
89 + 31573259 = 31573348
137 + 31573211 = 31573348
197 + 31573151 = 31573348
239 + 31573109 = 31573348
311 + 31573037 = 31573348
467 + 31572881 = 31573348
479 + 31572869 = 31573348

Showing the first eight; more decompositions exist.
