Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025240, here are decompositions:

31 + 1025209 = 1025240
37 + 1025203 = 1025240
43 + 1025197 = 1025240
79 + 1025161 = 1025240
103 + 1025137 = 1025240
127 + 1025113 = 1025240
193 + 1025047 = 1025240
211 + 1025029 = 1025240

Showing the first eight; more decompositions exist.
