Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556932, here are decompositions:

23 + 31556909 = 31556932
191 + 31556741 = 31556932
293 + 31556639 = 31556932
431 + 31556501 = 31556932
443 + 31556489 = 31556932
509 + 31556423 = 31556932
653 + 31556279 = 31556932
683 + 31556249 = 31556932

Showing the first eight; more decompositions exist.
