Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556776, here are decompositions:

5 + 31556771 = 31556776
29 + 31556747 = 31556776
89 + 31556687 = 31556776
137 + 31556639 = 31556776
239 + 31556537 = 31556776
353 + 31556423 = 31556776
359 + 31556417 = 31556776
467 + 31556309 = 31556776

Showing the first eight; more decompositions exist.
