Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485326, here are decompositions:

7 + 31485319 = 31485326
13 + 31485313 = 31485326
43 + 31485283 = 31485326
79 + 31485247 = 31485326
277 + 31485049 = 31485326
307 + 31485019 = 31485326
337 + 31484989 = 31485326
463 + 31484863 = 31485326

Showing the first eight; more decompositions exist.
