Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025920, here are decompositions:

3 + 1025917 = 1025920
11 + 1025909 = 1025920
23 + 1025897 = 1025920
29 + 1025891 = 1025920
47 + 1025873 = 1025920
101 + 1025819 = 1025920
113 + 1025807 = 1025920
131 + 1025789 = 1025920

Showing the first eight; more decompositions exist.
