Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496176, here are decompositions:

3 + 31496173 = 31496176
53 + 31496123 = 31496176
149 + 31496027 = 31496176
197 + 31495979 = 31496176
227 + 31495949 = 31496176
317 + 31495859 = 31496176
419 + 31495757 = 31496176
443 + 31495733 = 31496176

Showing the first eight; more decompositions exist.
