Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038186, here are decompositions:

29 + 1038157 = 1038186
43 + 1038143 = 1038186
59 + 1038127 = 1038186
67 + 1038119 = 1038186
109 + 1038077 = 1038186
113 + 1038073 = 1038186
139 + 1038047 = 1038186
157 + 1038029 = 1038186

Showing the first eight; more decompositions exist.
