Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023868, here are decompositions:

11 + 1023857 = 1023868
17 + 1023851 = 1023868
29 + 1023839 = 1023868
47 + 1023821 = 1023868
137 + 1023731 = 1023868
149 + 1023719 = 1023868
311 + 1023557 = 1023868
317 + 1023551 = 1023868

Showing the first eight; more decompositions exist.
