Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051530, here are decompositions:

23 + 1051507 = 1051530
31 + 1051499 = 1051530
59 + 1051471 = 1051530
61 + 1051469 = 1051530
71 + 1051459 = 1051530
107 + 1051423 = 1051530
113 + 1051417 = 1051530
157 + 1051373 = 1051530

Showing the first eight; more decompositions exist.
