Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051648, here are decompositions:

5 + 1051643 = 1051648
29 + 1051619 = 1051648
41 + 1051607 = 1051648
47 + 1051601 = 1051648
89 + 1051559 = 1051648
149 + 1051499 = 1051648
167 + 1051481 = 1051648
179 + 1051469 = 1051648

Showing the first eight; more decompositions exist.
