Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596574, here are decompositions:

3 + 31596571 = 31596574
101 + 31596473 = 31596574
137 + 31596437 = 31596574
173 + 31596401 = 31596574
257 + 31596317 = 31596574
263 + 31596311 = 31596574
281 + 31596293 = 31596574
431 + 31596143 = 31596574

Showing the first eight; more decompositions exist.
