Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025190, here are decompositions:

29 + 1025161 = 1025190
37 + 1025153 = 1025190
41 + 1025149 = 1025190
43 + 1025147 = 1025190
53 + 1025137 = 1025190
71 + 1025119 = 1025190
79 + 1025111 = 1025190
97 + 1025093 = 1025190

Showing the first eight; more decompositions exist.
