Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460248, here are decompositions:

311 + 31459937 = 31460248
317 + 31459931 = 31460248
389 + 31459859 = 31460248
401 + 31459847 = 31460248
419 + 31459829 = 31460248
569 + 31459679 = 31460248
587 + 31459661 = 31460248
761 + 31459487 = 31460248

Showing the first eight; more decompositions exist.
