Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103186, here are decompositions:

3 + 103183 = 103186
107 + 103079 = 103186
137 + 103049 = 103186
179 + 103007 = 103186
233 + 102953 = 103186
257 + 102929 = 103186
389 + 102797 = 103186
509 + 102677 = 103186

Showing the first eight; more decompositions exist.
