Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1052540, here are decompositions:

3 + 1052537 = 1052540
7 + 1052533 = 1052540
61 + 1052479 = 1052540
67 + 1052473 = 1052540
103 + 1052437 = 1052540
109 + 1052431 = 1052540
127 + 1052413 = 1052540
211 + 1052329 = 1052540

Showing the first eight; more decompositions exist.
