Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18932, here are decompositions:

13 + 18919 = 18932
19 + 18913 = 18932
73 + 18859 = 18932
139 + 18793 = 18932
241 + 18691 = 18932
271 + 18661 = 18932
349 + 18583 = 18932
379 + 18553 = 18932

Showing the first eight; more decompositions exist.
