Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028904, here are decompositions:

11 + 1028893 = 1028904
31 + 1028873 = 1028904
61 + 1028843 = 1028904
67 + 1028837 = 1028904
101 + 1028803 = 1028904
127 + 1028777 = 1028904
131 + 1028773 = 1028904
157 + 1028747 = 1028904

Showing the first eight; more decompositions exist.
