Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530964, here are decompositions:

5 + 31530959 = 31530964
71 + 31530893 = 31530964
131 + 31530833 = 31530964
137 + 31530827 = 31530964
167 + 31530797 = 31530964
191 + 31530773 = 31530964
251 + 31530713 = 31530964
263 + 31530701 = 31530964

Showing the first eight; more decompositions exist.
