Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177186, here are decompositions:

13 + 177173 = 177186
19 + 177167 = 177186
59 + 177127 = 177186
73 + 177113 = 177186
167 + 177019 = 177186
173 + 177013 = 177186
179 + 177007 = 177186
197 + 176989 = 177186

Showing the first eight; more decompositions exist.
