Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005458, here are decompositions:

19 + 1005439 = 1005458
31 + 1005427 = 1005458
67 + 1005391 = 1005458
109 + 1005349 = 1005458
127 + 1005331 = 1005458
229 + 1005229 = 1005458
241 + 1005217 = 1005458
271 + 1005187 = 1005458

Showing the first eight; more decompositions exist.
