Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465316, here are decompositions:

7 + 31465309 = 31465316
73 + 31465243 = 31465316
139 + 31465177 = 31465316
163 + 31465153 = 31465316
193 + 31465123 = 31465316
277 + 31465039 = 31465316
283 + 31465033 = 31465316
313 + 31465003 = 31465316

Showing the first eight; more decompositions exist.
