Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020440, here are decompositions:

61 + 1020379 = 1020440
79 + 1020361 = 1020440
103 + 1020337 = 1020440
139 + 1020301 = 1020440
181 + 1020259 = 1020440
193 + 1020247 = 1020440
277 + 1020163 = 1020440
283 + 1020157 = 1020440

Showing the first eight; more decompositions exist.
