Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178998, here are decompositions:

11 + 178987 = 178998
47 + 178951 = 178998
59 + 178939 = 178998
67 + 178931 = 178998
89 + 178909 = 178998
101 + 178897 = 178998
109 + 178889 = 178998
139 + 178859 = 178998

Showing the first eight; more decompositions exist.
