Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1052138, here are decompositions:

19 + 1052119 = 1052138
97 + 1052041 = 1052138
151 + 1051987 = 1052138
181 + 1051957 = 1052138
211 + 1051927 = 1052138
349 + 1051789 = 1052138
379 + 1051759 = 1052138
421 + 1051717 = 1052138

Showing the first eight; more decompositions exist.
