Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481176, here are decompositions:

5 + 31481171 = 31481176
17 + 31481159 = 31481176
53 + 31481123 = 31481176
137 + 31481039 = 31481176
227 + 31480949 = 31481176
257 + 31480919 = 31481176
263 + 31480913 = 31481176
347 + 31480829 = 31481176

Showing the first eight; more decompositions exist.
