Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485794, here are decompositions:

3 + 31485791 = 31485794
37 + 31485757 = 31485794
73 + 31485721 = 31485794
211 + 31485583 = 31485794
367 + 31485427 = 31485794
397 + 31485397 = 31485794
547 + 31485247 = 31485794
601 + 31485193 = 31485794

Showing the first eight; more decompositions exist.
