Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025320, here are decompositions:

17 + 1025303 = 1025320
41 + 1025279 = 1025320
47 + 1025273 = 1025320
53 + 1025267 = 1025320
59 + 1025261 = 1025320
89 + 1025231 = 1025320
167 + 1025153 = 1025320
173 + 1025147 = 1025320

Showing the first eight; more decompositions exist.
