Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18546, here are decompositions:

5 + 18541 = 18546
7 + 18539 = 18546
23 + 18523 = 18546
29 + 18517 = 18546
43 + 18503 = 18546
53 + 18493 = 18546
89 + 18457 = 18546
103 + 18443 = 18546

Showing the first eight; more decompositions exist.
