Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025020, here are decompositions:

11 + 1025009 = 1025020
23 + 1024997 = 1025020
89 + 1024931 = 1025020
137 + 1024883 = 1025020
149 + 1024871 = 1025020
167 + 1024853 = 1025020
197 + 1024823 = 1025020
263 + 1024757 = 1025020

Showing the first eight; more decompositions exist.
