Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025426, here are decompositions:

7 + 1025419 = 1025426
13 + 1025413 = 1025426
19 + 1025407 = 1025426
43 + 1025383 = 1025426
79 + 1025347 = 1025426
223 + 1025203 = 1025426
229 + 1025197 = 1025426
277 + 1025149 = 1025426

Showing the first eight; more decompositions exist.
