Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481334, here are decompositions:

13 + 31481321 = 31481334
41 + 31481293 = 31481334
83 + 31481251 = 31481334
97 + 31481237 = 31481334
103 + 31481231 = 31481334
127 + 31481207 = 31481334
163 + 31481171 = 31481334
191 + 31481143 = 31481334

Showing the first eight; more decompositions exist.
