Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99730, here are decompositions:

11 + 99719 = 99730
17 + 99713 = 99730
23 + 99707 = 99730
41 + 99689 = 99730
107 + 99623 = 99730
149 + 99581 = 99730
167 + 99563 = 99730
179 + 99551 = 99730

Showing the first eight; more decompositions exist.
