Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465332, here are decompositions:

11 + 31465321 = 31465332
23 + 31465309 = 31465332
43 + 31465289 = 31465332
89 + 31465243 = 31465332
109 + 31465223 = 31465332
139 + 31465193 = 31465332
149 + 31465183 = 31465332
179 + 31465153 = 31465332

Showing the first eight; more decompositions exist.
