Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614378, here are decompositions:

7 + 31614371 = 31614378
101 + 31614277 = 31614378
149 + 31614229 = 31614378
151 + 31614227 = 31614378
167 + 31614211 = 31614378
179 + 31614199 = 31614378
181 + 31614197 = 31614378
197 + 31614181 = 31614378

Showing the first eight; more decompositions exist.
