Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519060, here are decompositions:

3 + 31519057 = 31519060
11 + 31519049 = 31519060
71 + 31518989 = 31519060
107 + 31518953 = 31519060
137 + 31518923 = 31519060
179 + 31518881 = 31519060
191 + 31518869 = 31519060
197 + 31518863 = 31519060

Showing the first eight; more decompositions exist.
