Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051388, here are decompositions:

97 + 1051291 = 1051388
211 + 1051177 = 1051388
241 + 1051147 = 1051388
307 + 1051081 = 1051388
337 + 1051051 = 1051388
379 + 1051009 = 1051388
439 + 1050949 = 1051388
487 + 1050901 = 1051388

Showing the first eight; more decompositions exist.
