Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463922, here are decompositions:

11 + 31463911 = 31463922
13 + 31463909 = 31463922
29 + 31463893 = 31463922
31 + 31463891 = 31463922
43 + 31463879 = 31463922
73 + 31463849 = 31463922
79 + 31463843 = 31463922
163 + 31463759 = 31463922

Showing the first eight; more decompositions exist.
