Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002458, here are decompositions:

7 + 1002451 = 1002458
31 + 1002427 = 1002458
97 + 1002361 = 1002458
109 + 1002349 = 1002458
199 + 1002259 = 1002458
211 + 1002247 = 1002458
307 + 1002151 = 1002458
337 + 1002121 = 1002458

Showing the first eight; more decompositions exist.
