Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023808, here are decompositions:

89 + 1023719 = 1023808
251 + 1023557 = 1023808
257 + 1023551 = 1023808
347 + 1023461 = 1023808
389 + 1023419 = 1023808
419 + 1023389 = 1023808
479 + 1023329 = 1023808
491 + 1023317 = 1023808

Showing the first eight; more decompositions exist.
