Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465362, here are decompositions:

41 + 31465321 = 31465362
53 + 31465309 = 31465362
73 + 31465289 = 31465362
139 + 31465223 = 31465362
179 + 31465183 = 31465362
233 + 31465129 = 31465362
239 + 31465123 = 31465362
251 + 31465111 = 31465362

Showing the first eight; more decompositions exist.
