Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025560, here are decompositions:

17 + 1025543 = 1025560
23 + 1025537 = 1025560
47 + 1025513 = 1025560
83 + 1025477 = 1025560
101 + 1025459 = 1025560
167 + 1025393 = 1025560
227 + 1025333 = 1025560
233 + 1025327 = 1025560

Showing the first eight; more decompositions exist.
