Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178018, here are decompositions:

17 + 178001 = 178018
89 + 177929 = 178018
101 + 177917 = 178018
131 + 177887 = 178018
179 + 177839 = 178018
227 + 177791 = 178018
257 + 177761 = 178018
479 + 177539 = 178018

Showing the first eight; more decompositions exist.
