Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005436, here are decompositions:

23 + 1005413 = 1005436
149 + 1005287 = 1005436
167 + 1005269 = 1005436
197 + 1005239 = 1005436
227 + 1005209 = 1005436
233 + 1005203 = 1005436
293 + 1005143 = 1005436
449 + 1004987 = 1005436

Showing the first eight; more decompositions exist.
