Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99740, here are decompositions:

7 + 99733 = 99740
19 + 99721 = 99740
31 + 99709 = 99740
61 + 99679 = 99740
73 + 99667 = 99740
79 + 99661 = 99740
97 + 99643 = 99740
163 + 99577 = 99740

Showing the first eight; more decompositions exist.
