Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516892, here are decompositions:

3 + 31516889 = 31516892
13 + 31516879 = 31516892
73 + 31516819 = 31516892
103 + 31516789 = 31516892
139 + 31516753 = 31516892
163 + 31516729 = 31516892
193 + 31516699 = 31516892
223 + 31516669 = 31516892

Showing the first eight; more decompositions exist.
