Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465536, here are decompositions:

7 + 31465529 = 31465536
173 + 31465363 = 31465536
227 + 31465309 = 31465536
293 + 31465243 = 31465536
313 + 31465223 = 31465536
353 + 31465183 = 31465536
359 + 31465177 = 31465536
383 + 31465153 = 31465536

Showing the first eight; more decompositions exist.
