Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18954, here are decompositions:

7 + 18947 = 18954
37 + 18917 = 18954
41 + 18913 = 18954
43 + 18911 = 18954
151 + 18803 = 18954
157 + 18797 = 18954
167 + 18787 = 18954
181 + 18773 = 18954

Showing the first eight; more decompositions exist.
