Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005188, here are decompositions:

109 + 1005079 = 1005188
139 + 1005049 = 1005188
181 + 1005007 = 1005188
211 + 1004977 = 1005188
271 + 1004917 = 1005188
277 + 1004911 = 1005188
409 + 1004779 = 1005188
439 + 1004749 = 1005188

Showing the first eight; more decompositions exist.
