Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000730, here are decompositions:

7 + 1000723 = 1000730
61 + 1000669 = 1000730
79 + 1000651 = 1000730
109 + 1000621 = 1000730
151 + 1000579 = 1000730
193 + 1000537 = 1000730
223 + 1000507 = 1000730
277 + 1000453 = 1000730

Showing the first eight; more decompositions exist.
