Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10398, here are decompositions:

7 + 10391 = 10398
29 + 10369 = 10398
41 + 10357 = 10398
61 + 10337 = 10398
67 + 10331 = 10398
97 + 10301 = 10398
109 + 10289 = 10398
127 + 10271 = 10398

Showing the first eight; more decompositions exist.
