Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18532, here are decompositions:

11 + 18521 = 18532
29 + 18503 = 18532
71 + 18461 = 18532
89 + 18443 = 18532
131 + 18401 = 18532
179 + 18353 = 18532
191 + 18341 = 18532
263 + 18269 = 18532

Showing the first eight; more decompositions exist.
