Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31521314, here are decompositions:

3 + 31521311 = 31521314
43 + 31521271 = 31521314
157 + 31521157 = 31521314
277 + 31521037 = 31521314
283 + 31521031 = 31521314
313 + 31521001 = 31521314
337 + 31520977 = 31521314
397 + 31520917 = 31521314

Showing the first eight; more decompositions exist.
