Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005206, here are decompositions:

3 + 1005203 = 1005206
19 + 1005187 = 1005206
73 + 1005133 = 1005206
127 + 1005079 = 1005206
157 + 1005049 = 1005206
193 + 1005013 = 1005206
199 + 1005007 = 1005206
229 + 1004977 = 1005206

Showing the first eight; more decompositions exist.
