Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556754, here are decompositions:

7 + 31556747 = 31556754
13 + 31556741 = 31556754
17 + 31556737 = 31556754
67 + 31556687 = 31556754
101 + 31556653 = 31556754
107 + 31556647 = 31556754
197 + 31556557 = 31556754
277 + 31556477 = 31556754

Showing the first eight; more decompositions exist.
