Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460794, here are decompositions:

3 + 31460791 = 31460794
11 + 31460783 = 31460794
137 + 31460657 = 31460794
257 + 31460537 = 31460794
311 + 31460483 = 31460794
353 + 31460441 = 31460794
503 + 31460291 = 31460794
857 + 31459937 = 31460794

Showing the first eight; more decompositions exist.
