Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022998, here are decompositions:

17 + 1022981 = 1022998
107 + 1022891 = 1022998
149 + 1022849 = 1022998
269 + 1022729 = 1022998
359 + 1022639 = 1022998
467 + 1022531 = 1022998
479 + 1022519 = 1022998
491 + 1022507 = 1022998

Showing the first eight; more decompositions exist.
