Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465392, here are decompositions:

29 + 31465363 = 31465392
71 + 31465321 = 31465392
83 + 31465309 = 31465392
103 + 31465289 = 31465392
149 + 31465243 = 31465392
199 + 31465193 = 31465392
239 + 31465153 = 31465392
263 + 31465129 = 31465392

Showing the first eight; more decompositions exist.
