Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99940, here are decompositions:

11 + 99929 = 99940
17 + 99923 = 99940
59 + 99881 = 99940
101 + 99839 = 99940
107 + 99833 = 99940
131 + 99809 = 99940
173 + 99767 = 99940
179 + 99761 = 99940

Showing the first eight; more decompositions exist.
