Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178994, here are decompositions:

7 + 178987 = 178994
43 + 178951 = 178994
61 + 178933 = 178994
73 + 178921 = 178994
97 + 178897 = 178994
163 + 178831 = 178994
181 + 178813 = 178994
241 + 178753 = 178994

Showing the first eight; more decompositions exist.
