Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726730, here are decompositions:

7 + 8726723 = 8726730
17 + 8726713 = 8726730
31 + 8726699 = 8726730
43 + 8726687 = 8726730
53 + 8726677 = 8726730
59 + 8726671 = 8726730
83 + 8726647 = 8726730
97 + 8726633 = 8726730

Showing the first eight; more decompositions exist.
