Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31561594, here are decompositions:

17 + 31561577 = 31561594
47 + 31561547 = 31561594
131 + 31561463 = 31561594
137 + 31561457 = 31561594
173 + 31561421 = 31561594
191 + 31561403 = 31561594
293 + 31561301 = 31561594
347 + 31561247 = 31561594

Showing the first eight; more decompositions exist.
