Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023998, here are decompositions:

7 + 1023991 = 1023998
127 + 1023871 = 1023998
229 + 1023769 = 1023998
277 + 1023721 = 1023998
397 + 1023601 = 1023998
421 + 1023577 = 1023998
457 + 1023541 = 1023998
499 + 1023499 = 1023998

Showing the first eight; more decompositions exist.
