Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012730, here are decompositions:

13 + 1012717 = 1012730
31 + 1012699 = 1012730
67 + 1012663 = 1012730
73 + 1012657 = 1012730
97 + 1012633 = 1012730
139 + 1012591 = 1012730
157 + 1012573 = 1012730
181 + 1012549 = 1012730

Showing the first eight; more decompositions exist.
