Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000406, here are decompositions:

3 + 1000403 = 1000406
13 + 1000393 = 1000406
73 + 1000333 = 1000406
103 + 1000303 = 1000406
157 + 1000249 = 1000406
193 + 1000213 = 1000406
223 + 1000183 = 1000406
307 + 1000099 = 1000406

Showing the first eight; more decompositions exist.
