Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533964, here are decompositions:

5 + 31533959 = 31533964
41 + 31533923 = 31533964
53 + 31533911 = 31533964
131 + 31533833 = 31533964
173 + 31533791 = 31533964
191 + 31533773 = 31533964
257 + 31533707 = 31533964
353 + 31533611 = 31533964

Showing the first eight; more decompositions exist.
