Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99930, here are decompositions:

7 + 99923 = 99930
23 + 99907 = 99930
29 + 99901 = 99930
53 + 99877 = 99930
59 + 99871 = 99930
71 + 99859 = 99930
97 + 99833 = 99930
101 + 99829 = 99930

Showing the first eight; more decompositions exist.
