Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18450, here are decompositions:

7 + 18443 = 18450
11 + 18439 = 18450
17 + 18433 = 18450
23 + 18427 = 18450
37 + 18413 = 18450
53 + 18397 = 18450
71 + 18379 = 18450
79 + 18371 = 18450

Showing the first eight; more decompositions exist.
