Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055432, here are decompositions:

3 + 1055429 = 1055432
19 + 1055413 = 1055432
61 + 1055371 = 1055432
73 + 1055359 = 1055432
163 + 1055269 = 1055432
181 + 1055251 = 1055432
199 + 1055233 = 1055432
241 + 1055191 = 1055432

Showing the first eight; more decompositions exist.
