Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051398, here are decompositions:

79 + 1051319 = 1051398
97 + 1051301 = 1051398
107 + 1051291 = 1051398
151 + 1051247 = 1051398
241 + 1051157 = 1051398
251 + 1051147 = 1051398
317 + 1051081 = 1051398
347 + 1051051 = 1051398

Showing the first eight; more decompositions exist.
