Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051630, here are decompositions:

11 + 1051619 = 1051630
23 + 1051607 = 1051630
29 + 1051601 = 1051630
59 + 1051571 = 1051630
71 + 1051559 = 1051630
131 + 1051499 = 1051630
149 + 1051481 = 1051630
233 + 1051397 = 1051630

Showing the first eight; more decompositions exist.
