Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463992, here are decompositions:

29 + 31463963 = 31463992
71 + 31463921 = 31463992
83 + 31463909 = 31463992
101 + 31463891 = 31463992
113 + 31463879 = 31463992
149 + 31463843 = 31463992
233 + 31463759 = 31463992
311 + 31463681 = 31463992

Showing the first eight; more decompositions exist.
