Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465374, here are decompositions:

11 + 31465363 = 31465374
53 + 31465321 = 31465374
131 + 31465243 = 31465374
151 + 31465223 = 31465374
181 + 31465193 = 31465374
191 + 31465183 = 31465374
197 + 31465177 = 31465374
251 + 31465123 = 31465374

Showing the first eight; more decompositions exist.
