Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497316, here are decompositions:

3 + 31497313 = 31497316
17 + 31497299 = 31497316
23 + 31497293 = 31497316
29 + 31497287 = 31497316
233 + 31497083 = 31497316
353 + 31496963 = 31497316
359 + 31496957 = 31497316
443 + 31496873 = 31497316

Showing the first eight; more decompositions exist.
