Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600566, here are decompositions:

17 + 31600549 = 31600566
37 + 31600529 = 31600566
43 + 31600523 = 31600566
73 + 31600493 = 31600566
113 + 31600453 = 31600566
157 + 31600409 = 31600566
233 + 31600333 = 31600566
293 + 31600273 = 31600566

Showing the first eight; more decompositions exist.
