Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556692, here are decompositions:

5 + 31556687 = 31556692
53 + 31556639 = 31556692
191 + 31556501 = 31556692
269 + 31556423 = 31556692
311 + 31556381 = 31556692
383 + 31556309 = 31556692
389 + 31556303 = 31556692
443 + 31556249 = 31556692

Showing the first eight; more decompositions exist.
