Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465284, here are decompositions:

41 + 31465243 = 31465284
61 + 31465223 = 31465284
101 + 31465183 = 31465284
107 + 31465177 = 31465284
131 + 31465153 = 31465284
173 + 31465111 = 31465284
223 + 31465061 = 31465284
251 + 31465033 = 31465284

Showing the first eight; more decompositions exist.
