Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560964, here are decompositions:

23 + 31560941 = 31560964
53 + 31560911 = 31560964
101 + 31560863 = 31560964
167 + 31560797 = 31560964
173 + 31560791 = 31560964
233 + 31560731 = 31560964
251 + 31560713 = 31560964
317 + 31560647 = 31560964

Showing the first eight; more decompositions exist.
