Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507796, here are decompositions:

3 + 31507793 = 31507796
7 + 31507789 = 31507796
43 + 31507753 = 31507796
97 + 31507699 = 31507796
163 + 31507633 = 31507796
223 + 31507573 = 31507796
337 + 31507459 = 31507796
433 + 31507363 = 31507796

Showing the first eight; more decompositions exist.
