Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051420, here are decompositions:

3 + 1051417 = 1051420
11 + 1051409 = 1051420
23 + 1051397 = 1051420
47 + 1051373 = 1051420
101 + 1051319 = 1051420
107 + 1051313 = 1051420
137 + 1051283 = 1051420
173 + 1051247 = 1051420

Showing the first eight; more decompositions exist.
