Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596474, here are decompositions:

37 + 31596437 = 31596474
61 + 31596413 = 31596474
71 + 31596403 = 31596474
73 + 31596401 = 31596474
83 + 31596391 = 31596474
157 + 31596317 = 31596474
163 + 31596311 = 31596474
167 + 31596307 = 31596474

Showing the first eight; more decompositions exist.
