Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178954, here are decompositions:

3 + 178951 = 178954
23 + 178931 = 178954
47 + 178907 = 178954
101 + 178853 = 178954
137 + 178817 = 178954
173 + 178781 = 178954
197 + 178757 = 178954
257 + 178697 = 178954

Showing the first eight; more decompositions exist.
