Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005212, here are decompositions:

3 + 1005209 = 1005212
79 + 1005133 = 1005212
139 + 1005073 = 1005212
163 + 1005049 = 1005212
193 + 1005019 = 1005212
199 + 1005013 = 1005212
433 + 1004779 = 1005212
463 + 1004749 = 1005212

Showing the first eight; more decompositions exist.
