Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519196, here are decompositions:

3 + 31519193 = 31519196
97 + 31519099 = 31519196
127 + 31519069 = 31519196
139 + 31519057 = 31519196
283 + 31518913 = 31519196
337 + 31518859 = 31519196
439 + 31518757 = 31519196
523 + 31518673 = 31519196

Showing the first eight; more decompositions exist.
