Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8186, here are decompositions:

7 + 8179 = 8186
19 + 8167 = 8186
97 + 8089 = 8186
127 + 8059 = 8186
193 + 7993 = 8186
223 + 7963 = 8186
307 + 7879 = 8186
313 + 7873 = 8186

Showing the first eight; more decompositions exist.
