Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025156, here are decompositions:

3 + 1025153 = 1025156
7 + 1025149 = 1025156
19 + 1025137 = 1025156
37 + 1025119 = 1025156
43 + 1025113 = 1025156
109 + 1025047 = 1025156
127 + 1025029 = 1025156
193 + 1024963 = 1025156

Showing the first eight; more decompositions exist.
