Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18636, here are decompositions:

19 + 18617 = 18636
43 + 18593 = 18636
53 + 18583 = 18636
83 + 18553 = 18636
97 + 18539 = 18636
113 + 18523 = 18636
179 + 18457 = 18636
193 + 18443 = 18636

Showing the first eight; more decompositions exist.
