Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463332, here are decompositions:

3 + 31463329 = 31463332
11 + 31463321 = 31463332
71 + 31463261 = 31463332
83 + 31463249 = 31463332
233 + 31463099 = 31463332
269 + 31463063 = 31463332
353 + 31462979 = 31463332
401 + 31462931 = 31463332

Showing the first eight; more decompositions exist.
