Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11556, here are decompositions:

5 + 11551 = 11556
7 + 11549 = 11556
29 + 11527 = 11556
37 + 11519 = 11556
53 + 11503 = 11556
59 + 11497 = 11556
67 + 11489 = 11556
73 + 11483 = 11556

Showing the first eight; more decompositions exist.
