Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99880, here are decompositions:

3 + 99877 = 99880
41 + 99839 = 99880
47 + 99833 = 99880
71 + 99809 = 99880
113 + 99767 = 99880
167 + 99713 = 99880
173 + 99707 = 99880
191 + 99689 = 99880

Showing the first eight; more decompositions exist.
