Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519062, here are decompositions:

5 + 31519057 = 31519062
13 + 31519049 = 31519062
73 + 31518989 = 31519062
101 + 31518961 = 31519062
109 + 31518953 = 31519062
139 + 31518923 = 31519062
149 + 31518913 = 31519062
163 + 31518899 = 31519062

Showing the first eight; more decompositions exist.
