Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467794, here are decompositions:

31 + 31467763 = 31467794
67 + 31467727 = 31467794
73 + 31467721 = 31467794
103 + 31467691 = 31467794
223 + 31467571 = 31467794
313 + 31467481 = 31467794
613 + 31467181 = 31467794
661 + 31467133 = 31467794

Showing the first eight; more decompositions exist.
