Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519074, here are decompositions:

5 + 31519069 = 31519074
7 + 31519067 = 31519074
17 + 31519057 = 31519074
113 + 31518961 = 31519074
151 + 31518923 = 31519074
193 + 31518881 = 31519074
211 + 31518863 = 31519074
281 + 31518793 = 31519074

Showing the first eight; more decompositions exist.
