Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464794, here are decompositions:

7 + 31464787 = 31464794
13 + 31464781 = 31464794
37 + 31464757 = 31464794
223 + 31464571 = 31464794
313 + 31464481 = 31464794
331 + 31464463 = 31464794
367 + 31464427 = 31464794
373 + 31464421 = 31464794

Showing the first eight; more decompositions exist.
