Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18430, here are decompositions:

3 + 18427 = 18430
17 + 18413 = 18430
29 + 18401 = 18430
59 + 18371 = 18430
89 + 18341 = 18430
101 + 18329 = 18430
173 + 18257 = 18430
179 + 18251 = 18430

Showing the first eight; more decompositions exist.
