Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596746, here are decompositions:

3 + 31596743 = 31596746
37 + 31596709 = 31596746
67 + 31596679 = 31596746
73 + 31596673 = 31596746
109 + 31596637 = 31596746
163 + 31596583 = 31596746
193 + 31596553 = 31596746
367 + 31596379 = 31596746

Showing the first eight; more decompositions exist.
