Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178056, here are decompositions:

17 + 178039 = 178056
19 + 178037 = 178056
89 + 177967 = 178056
103 + 177953 = 178056
107 + 177949 = 178056
113 + 177943 = 178056
127 + 177929 = 178056
139 + 177917 = 178056

Showing the first eight; more decompositions exist.
