Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055398, here are decompositions:

11 + 1055387 = 1055398
131 + 1055267 = 1055398
137 + 1055261 = 1055398
167 + 1055231 = 1055398
257 + 1055141 = 1055398
359 + 1055039 = 1055398
467 + 1054931 = 1055398
677 + 1054721 = 1055398

Showing the first eight; more decompositions exist.
