Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460074, here are decompositions:

11 + 31460063 = 31460074
137 + 31459937 = 31460074
227 + 31459847 = 31460074
521 + 31459553 = 31460074
557 + 31459517 = 31460074
587 + 31459487 = 31460074
617 + 31459457 = 31460074
641 + 31459433 = 31460074

Showing the first eight; more decompositions exist.
