Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460284, here are decompositions:

3 + 31460281 = 31460284
5 + 31460279 = 31460284
17 + 31460267 = 31460284
347 + 31459937 = 31460284
353 + 31459931 = 31460284
431 + 31459853 = 31460284
587 + 31459697 = 31460284
617 + 31459667 = 31460284

Showing the first eight; more decompositions exist.
