Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055558, here are decompositions:

151 + 1055407 = 1055558
199 + 1055359 = 1055558
211 + 1055347 = 1055558
307 + 1055251 = 1055558
367 + 1055191 = 1055558
421 + 1055137 = 1055558
541 + 1055017 = 1055558
601 + 1054957 = 1055558

Showing the first eight; more decompositions exist.
