Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051578, here are decompositions:

7 + 1051571 = 1051578
19 + 1051559 = 1051578
29 + 1051549 = 1051578
71 + 1051507 = 1051578
79 + 1051499 = 1051578
97 + 1051481 = 1051578
107 + 1051471 = 1051578
109 + 1051469 = 1051578

Showing the first eight; more decompositions exist.
