Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465446, here are decompositions:

29 + 31465417 = 31465446
83 + 31465363 = 31465446
137 + 31465309 = 31465446
157 + 31465289 = 31465446
223 + 31465223 = 31465446
263 + 31465183 = 31465446
269 + 31465177 = 31465446
293 + 31465153 = 31465446

Showing the first eight; more decompositions exist.
