Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025018, here are decompositions:

31 + 1024987 = 1025018
61 + 1024957 = 1025018
67 + 1024951 = 1025018
79 + 1024939 = 1025018
97 + 1024921 = 1025018
109 + 1024909 = 1025018
307 + 1024711 = 1025018
349 + 1024669 = 1025018

Showing the first eight; more decompositions exist.
