Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463926, here are decompositions:

5 + 31463921 = 31463926
17 + 31463909 = 31463926
29 + 31463897 = 31463926
47 + 31463879 = 31463926
83 + 31463843 = 31463926
167 + 31463759 = 31463926
419 + 31463507 = 31463926
443 + 31463483 = 31463926

Showing the first eight; more decompositions exist.
