Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055540, here are decompositions:

37 + 1055503 = 1055540
103 + 1055437 = 1055540
127 + 1055413 = 1055540
181 + 1055359 = 1055540
193 + 1055347 = 1055540
271 + 1055269 = 1055540
307 + 1055233 = 1055540
349 + 1055191 = 1055540

Showing the first eight; more decompositions exist.
