Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055198, here are decompositions:

7 + 1055191 = 1055198
31 + 1055167 = 1055198
61 + 1055137 = 1055198
181 + 1055017 = 1055198
241 + 1054957 = 1055198
271 + 1054927 = 1055198
367 + 1054831 = 1055198
379 + 1054819 = 1055198

Showing the first eight; more decompositions exist.
