Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586274, here are decompositions:

17 + 31586257 = 31586274
37 + 31586237 = 31586274
103 + 31586171 = 31586274
127 + 31586147 = 31586274
173 + 31586101 = 31586274
197 + 31586077 = 31586274
271 + 31586003 = 31586274
277 + 31585997 = 31586274

Showing the first eight; more decompositions exist.
