Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556854, here are decompositions:

41 + 31556813 = 31556854
83 + 31556771 = 31556854
107 + 31556747 = 31556854
113 + 31556741 = 31556854
167 + 31556687 = 31556854
317 + 31556537 = 31556854
353 + 31556501 = 31556854
431 + 31556423 = 31556854

Showing the first eight; more decompositions exist.
