Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537494, here are decompositions:

13 + 31537481 = 31537494
17 + 31537477 = 31537494
61 + 31537433 = 31537494
103 + 31537391 = 31537494
167 + 31537327 = 31537494
181 + 31537313 = 31537494
223 + 31537271 = 31537494
227 + 31537267 = 31537494

Showing the first eight; more decompositions exist.
