Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660730, here are decompositions:

7 + 8660723 = 8660730
31 + 8660699 = 8660730
37 + 8660693 = 8660730
41 + 8660689 = 8660730
47 + 8660683 = 8660730
59 + 8660671 = 8660730
73 + 8660657 = 8660730
107 + 8660623 = 8660730

Showing the first eight; more decompositions exist.
