Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475026, here are decompositions:

17 + 31475009 = 31475026
29 + 31474997 = 31475026
197 + 31474829 = 31475026
263 + 31474763 = 31475026
293 + 31474733 = 31475026
353 + 31474673 = 31475026
449 + 31474577 = 31475026
467 + 31474559 = 31475026

Showing the first eight; more decompositions exist.
