Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474302, here are decompositions:

11 + 31474291 = 31474302
53 + 31474249 = 31474302
89 + 31474213 = 31474302
131 + 31474171 = 31474302
173 + 31474129 = 31474302
191 + 31474111 = 31474302
229 + 31474073 = 31474302
241 + 31474061 = 31474302

Showing the first eight; more decompositions exist.
