Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18550, here are decompositions:

11 + 18539 = 18550
29 + 18521 = 18550
47 + 18503 = 18550
89 + 18461 = 18550
107 + 18443 = 18550
137 + 18413 = 18550
149 + 18401 = 18550
179 + 18371 = 18550

Showing the first eight; more decompositions exist.
