Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599656, here are decompositions:

3 + 31599653 = 31599656
7 + 31599649 = 31599656
103 + 31599553 = 31599656
157 + 31599499 = 31599656
307 + 31599349 = 31599656
349 + 31599307 = 31599656
397 + 31599259 = 31599656
409 + 31599247 = 31599656

Showing the first eight; more decompositions exist.
