Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030286, here are decompositions:

67 + 1030219 = 1030286
73 + 1030213 = 1030286
349 + 1029937 = 1030286
379 + 1029907 = 1030286
463 + 1029823 = 1030286
643 + 1029643 = 1030286
709 + 1029577 = 1030286
739 + 1029547 = 1030286

Showing the first eight; more decompositions exist.
