Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18484, here are decompositions:

3 + 18481 = 18484
23 + 18461 = 18484
41 + 18443 = 18484
71 + 18413 = 18484
83 + 18401 = 18484
113 + 18371 = 18484
131 + 18353 = 18484
173 + 18311 = 18484

Showing the first eight; more decompositions exist.
