Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18372, here are decompositions:

5 + 18367 = 18372
19 + 18353 = 18372
31 + 18341 = 18372
43 + 18329 = 18372
59 + 18313 = 18372
61 + 18311 = 18372
71 + 18301 = 18372
83 + 18289 = 18372

Showing the first eight; more decompositions exist.
