Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005418, here are decompositions:

5 + 1005413 = 1005418
47 + 1005371 = 1005418
59 + 1005359 = 1005418
101 + 1005317 = 1005418
131 + 1005287 = 1005418
149 + 1005269 = 1005418
179 + 1005239 = 1005418
257 + 1005161 = 1005418

Showing the first eight; more decompositions exist.
