Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463794, here are decompositions:

113 + 31463681 = 31463794
311 + 31463483 = 31463794
317 + 31463477 = 31463794
431 + 31463363 = 31463794
647 + 31463147 = 31463794
863 + 31462931 = 31463794
983 + 31462811 = 31463794
1217 + 31462577 = 31463794

Showing the first eight; more decompositions exist.
