Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008128, here are decompositions:

97 + 1008031 = 1008128
127 + 1008001 = 1008128
151 + 1007977 = 1008128
157 + 1007971 = 1008128
241 + 1007887 = 1008128
271 + 1007857 = 1008128
379 + 1007749 = 1008128
397 + 1007731 = 1008128

Showing the first eight; more decompositions exist.
