Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40556, here are decompositions:

13 + 40543 = 40556
37 + 40519 = 40556
73 + 40483 = 40556
97 + 40459 = 40556
127 + 40429 = 40556
199 + 40357 = 40556
367 + 40189 = 40556
379 + 40177 = 40556

Showing the first eight; more decompositions exist.
