Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11636, here are decompositions:

3 + 11633 = 11636
19 + 11617 = 11636
43 + 11593 = 11636
109 + 11527 = 11636
139 + 11497 = 11636
193 + 11443 = 11636
199 + 11437 = 11636
283 + 11353 = 11636

Showing the first eight; more decompositions exist.
