Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023398, here are decompositions:

7 + 1023391 = 1023398
31 + 1023367 = 1023398
37 + 1023361 = 1023398
97 + 1023301 = 1023398
109 + 1023289 = 1023398
139 + 1023259 = 1023398
199 + 1023199 = 1023398
331 + 1023067 = 1023398

Showing the first eight; more decompositions exist.
