Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465266, here are decompositions:

23 + 31465243 = 31465266
43 + 31465223 = 31465266
73 + 31465193 = 31465266
83 + 31465183 = 31465266
89 + 31465177 = 31465266
113 + 31465153 = 31465266
137 + 31465129 = 31465266
167 + 31465099 = 31465266

Showing the first eight; more decompositions exist.
