Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99800, here are decompositions:

7 + 99793 = 99800
13 + 99787 = 99800
67 + 99733 = 99800
79 + 99721 = 99800
139 + 99661 = 99800
157 + 99643 = 99800
193 + 99607 = 99800
223 + 99577 = 99800

Showing the first eight; more decompositions exist.
