Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556752, here are decompositions:

5 + 31556747 = 31556752
11 + 31556741 = 31556752
113 + 31556639 = 31556752
251 + 31556501 = 31556752
263 + 31556489 = 31556752
443 + 31556309 = 31556752
449 + 31556303 = 31556752
503 + 31556249 = 31556752

Showing the first eight; more decompositions exist.
