Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18374, here are decompositions:

3 + 18371 = 18374
7 + 18367 = 18374
61 + 18313 = 18374
67 + 18307 = 18374
73 + 18301 = 18374
151 + 18223 = 18374
157 + 18217 = 18374
163 + 18211 = 18374

Showing the first eight; more decompositions exist.
