Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026430, here are decompositions:

3 + 1026427 = 1026430
17 + 1026413 = 1026430
23 + 1026407 = 1026430
29 + 1026401 = 1026430
47 + 1026383 = 1026430
59 + 1026371 = 1026430
71 + 1026359 = 1026430
131 + 1026299 = 1026430

Showing the first eight; more decompositions exist.
