Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055420, here are decompositions:

7 + 1055413 = 1055420
13 + 1055407 = 1055420
61 + 1055359 = 1055420
73 + 1055347 = 1055420
151 + 1055269 = 1055420
229 + 1055191 = 1055420
277 + 1055143 = 1055420
283 + 1055137 = 1055420

Showing the first eight; more decompositions exist.
