Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474936, here are decompositions:

5 + 31474931 = 31474936
107 + 31474829 = 31474936
173 + 31474763 = 31474936
263 + 31474673 = 31474936
359 + 31474577 = 31474936
503 + 31474433 = 31474936
593 + 31474343 = 31474936
617 + 31474319 = 31474936

Showing the first eight; more decompositions exist.
