Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18270, here are decompositions:

13 + 18257 = 18270
17 + 18253 = 18270
19 + 18251 = 18270
37 + 18233 = 18270
41 + 18229 = 18270
47 + 18223 = 18270
53 + 18217 = 18270
59 + 18211 = 18270

Showing the first eight; more decompositions exist.
