Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474308, here are decompositions:

7 + 31474301 = 31474308
17 + 31474291 = 31474308
59 + 31474249 = 31474308
137 + 31474171 = 31474308
167 + 31474141 = 31474308
179 + 31474129 = 31474308
197 + 31474111 = 31474308
251 + 31474057 = 31474308

Showing the first eight; more decompositions exist.
