Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483936, here are decompositions:

17 + 31483919 = 31483936
23 + 31483913 = 31483936
47 + 31483889 = 31483936
53 + 31483883 = 31483936
59 + 31483877 = 31483936
137 + 31483799 = 31483936
353 + 31483583 = 31483936
359 + 31483577 = 31483936

Showing the first eight; more decompositions exist.
