Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460254, here are decompositions:

191 + 31460063 = 31460254
317 + 31459937 = 31460254
401 + 31459853 = 31460254
521 + 31459733 = 31460254
557 + 31459697 = 31460254
587 + 31459667 = 31460254
593 + 31459661 = 31460254
701 + 31459553 = 31460254

Showing the first eight; more decompositions exist.
