Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025680, here are decompositions:

11 + 1025669 = 1025680
59 + 1025621 = 1025680
101 + 1025579 = 1025680
137 + 1025543 = 1025680
167 + 1025513 = 1025680
197 + 1025483 = 1025680
263 + 1025417 = 1025680
347 + 1025333 = 1025680

Showing the first eight; more decompositions exist.
