Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025644, here are decompositions:

3 + 1025641 = 1025644
23 + 1025621 = 1025644
83 + 1025561 = 1025644
101 + 1025543 = 1025644
107 + 1025537 = 1025644
131 + 1025513 = 1025644
167 + 1025477 = 1025644
227 + 1025417 = 1025644

Showing the first eight; more decompositions exist.
