Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025540, here are decompositions:

3 + 1025537 = 1025540
31 + 1025509 = 1025540
37 + 1025503 = 1025540
97 + 1025443 = 1025540
127 + 1025413 = 1025540
157 + 1025383 = 1025540
193 + 1025347 = 1025540
283 + 1025257 = 1025540

Showing the first eight; more decompositions exist.
