Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516374, here are decompositions:

13 + 31516361 = 31516374
17 + 31516357 = 31516374
41 + 31516333 = 31516374
47 + 31516327 = 31516374
137 + 31516237 = 31516374
173 + 31516201 = 31516374
191 + 31516183 = 31516374
251 + 31516123 = 31516374

Showing the first eight; more decompositions exist.
