Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025180, here are decompositions:

19 + 1025161 = 1025180
31 + 1025149 = 1025180
43 + 1025137 = 1025180
61 + 1025119 = 1025180
67 + 1025113 = 1025180
151 + 1025029 = 1025180
193 + 1024987 = 1025180
223 + 1024957 = 1025180

Showing the first eight; more decompositions exist.
