Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556682, here are decompositions:

29 + 31556653 = 31556682
43 + 31556639 = 31556682
181 + 31556501 = 31556682
193 + 31556489 = 31556682
293 + 31556389 = 31556682
359 + 31556323 = 31556682
373 + 31556309 = 31556682
379 + 31556303 = 31556682

Showing the first eight; more decompositions exist.
