Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601746, here are decompositions:

3 + 31601743 = 31601746
23 + 31601723 = 31601746
47 + 31601699 = 31601746
179 + 31601567 = 31601746
233 + 31601513 = 31601746
257 + 31601489 = 31601746
353 + 31601393 = 31601746
389 + 31601357 = 31601746

Showing the first eight; more decompositions exist.
