Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492466, here are decompositions:

13 + 31492453 = 31492466
37 + 31492429 = 31492466
43 + 31492423 = 31492466
67 + 31492399 = 31492466
73 + 31492393 = 31492466
97 + 31492369 = 31492466
223 + 31492243 = 31492466
373 + 31492093 = 31492466

Showing the first eight; more decompositions exist.
