Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518964, here are decompositions:

3 + 31518961 = 31518964
11 + 31518953 = 31518964
41 + 31518923 = 31518964
83 + 31518881 = 31518964
101 + 31518863 = 31518964
137 + 31518827 = 31518964
311 + 31518653 = 31518964
317 + 31518647 = 31518964

Showing the first eight; more decompositions exist.
