Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99700, here are decompositions:

11 + 99689 = 99700
89 + 99611 = 99700
137 + 99563 = 99700
149 + 99551 = 99700
173 + 99527 = 99700
269 + 99431 = 99700
353 + 99347 = 99700
383 + 99317 = 99700

Showing the first eight; more decompositions exist.
