Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519134, here are decompositions:

13 + 31519121 = 31519134
43 + 31519091 = 31519134
61 + 31519073 = 31519134
67 + 31519067 = 31519134
173 + 31518961 = 31519134
181 + 31518953 = 31519134
211 + 31518923 = 31519134
271 + 31518863 = 31519134

Showing the first eight; more decompositions exist.
