Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025218, here are decompositions:

71 + 1025147 = 1025218
107 + 1025111 = 1025218
137 + 1025081 = 1025218
179 + 1025039 = 1025218
197 + 1025021 = 1025218
317 + 1024901 = 1025218
347 + 1024871 = 1025218
419 + 1024799 = 1025218

Showing the first eight; more decompositions exist.
