Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516346, here are decompositions:

13 + 31516333 = 31516346
19 + 31516327 = 31516346
109 + 31516237 = 31516346
157 + 31516189 = 31516346
163 + 31516183 = 31516346
193 + 31516153 = 31516346
223 + 31516123 = 31516346
397 + 31515949 = 31516346

Showing the first eight; more decompositions exist.
