Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025550, here are decompositions:

7 + 1025543 = 1025550
13 + 1025537 = 1025550
37 + 1025513 = 1025550
41 + 1025509 = 1025550
47 + 1025503 = 1025550
67 + 1025483 = 1025550
73 + 1025477 = 1025550
107 + 1025443 = 1025550

Showing the first eight; more decompositions exist.
