Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055378, here are decompositions:

7 + 1055371 = 1055378
19 + 1055359 = 1055378
31 + 1055347 = 1055378
109 + 1055269 = 1055378
127 + 1055251 = 1055378
211 + 1055167 = 1055378
241 + 1055137 = 1055378
421 + 1054957 = 1055378

Showing the first eight; more decompositions exist.
