Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100398, here are decompositions:

5 + 100393 = 100398
7 + 100391 = 100398
19 + 100379 = 100398
37 + 100361 = 100398
41 + 100357 = 100398
101 + 100297 = 100398
107 + 100291 = 100398
127 + 100271 = 100398

Showing the first eight; more decompositions exist.
