Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31521414, here are decompositions:

5 + 31521409 = 31521414
37 + 31521377 = 31521414
61 + 31521353 = 31521414
73 + 31521341 = 31521414
103 + 31521311 = 31521414
157 + 31521257 = 31521414
191 + 31521223 = 31521414
257 + 31521157 = 31521414

Showing the first eight; more decompositions exist.
