Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025730, here are decompositions:

23 + 1025707 = 1025730
37 + 1025693 = 1025730
61 + 1025669 = 1025730
71 + 1025659 = 1025730
89 + 1025641 = 1025730
107 + 1025623 = 1025730
109 + 1025621 = 1025730
151 + 1025579 = 1025730

Showing the first eight; more decompositions exist.
