Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025750, here are decompositions:

3 + 1025747 = 1025750
43 + 1025707 = 1025750
97 + 1025653 = 1025750
109 + 1025641 = 1025750
127 + 1025623 = 1025750
139 + 1025611 = 1025750
199 + 1025551 = 1025750
241 + 1025509 = 1025750

Showing the first eight; more decompositions exist.
