Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040138, here are decompositions:

19 + 1040119 = 1040138
37 + 1040101 = 1040138
67 + 1040071 = 1040138
79 + 1040059 = 1040138
109 + 1040029 = 1040138
139 + 1039999 = 1040138
241 + 1039897 = 1040138
349 + 1039789 = 1040138

Showing the first eight; more decompositions exist.
