Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519032, here are decompositions:

43 + 31518989 = 31519032
71 + 31518961 = 31519032
79 + 31518953 = 31519032
109 + 31518923 = 31519032
151 + 31518881 = 31519032
163 + 31518869 = 31519032
173 + 31518859 = 31519032
239 + 31518793 = 31519032

Showing the first eight; more decompositions exist.
