Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667730, here are decompositions:

3 + 8667727 = 8667730
23 + 8667707 = 8667730
41 + 8667689 = 8667730
53 + 8667677 = 8667730
89 + 8667641 = 8667730
167 + 8667563 = 8667730
191 + 8667539 = 8667730
233 + 8667497 = 8667730

Showing the first eight; more decompositions exist.
