Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18924, here are decompositions:

5 + 18919 = 18924
7 + 18917 = 18924
11 + 18913 = 18924
13 + 18911 = 18924
127 + 18797 = 18924
131 + 18793 = 18924
137 + 18787 = 18924
151 + 18773 = 18924

Showing the first eight; more decompositions exist.
