Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1052420, here are decompositions:

3 + 1052417 = 1052420
7 + 1052413 = 1052420
139 + 1052281 = 1052420
151 + 1052269 = 1052420
199 + 1052221 = 1052420
223 + 1052197 = 1052420
241 + 1052179 = 1052420
283 + 1052137 = 1052420

Showing the first eight; more decompositions exist.
