Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031138, here are decompositions:

19 + 1031119 = 1031138
151 + 1030987 = 1031138
181 + 1030957 = 1031138
271 + 1030867 = 1031138
307 + 1030831 = 1031138
337 + 1030801 = 1031138
379 + 1030759 = 1031138
397 + 1030741 = 1031138

Showing the first eight; more decompositions exist.
