Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051512, here are decompositions:

5 + 1051507 = 1051512
13 + 1051499 = 1051512
31 + 1051481 = 1051512
41 + 1051471 = 1051512
43 + 1051469 = 1051512
53 + 1051459 = 1051512
89 + 1051423 = 1051512
103 + 1051409 = 1051512

Showing the first eight; more decompositions exist.
