Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519734, here are decompositions:

23 + 31519711 = 31519734
31 + 31519703 = 31519734
47 + 31519687 = 31519734
61 + 31519673 = 31519734
73 + 31519661 = 31519734
151 + 31519583 = 31519734
163 + 31519571 = 31519734
167 + 31519567 = 31519734

Showing the first eight; more decompositions exist.
