Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18672, here are decompositions:

11 + 18661 = 18672
79 + 18593 = 18672
89 + 18583 = 18672
131 + 18541 = 18672
149 + 18523 = 18672
151 + 18521 = 18672
179 + 18493 = 18672
191 + 18481 = 18672

Showing the first eight; more decompositions exist.
