Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043686, here are decompositions:

3 + 1043683 = 1043686
23 + 1043663 = 1043686
29 + 1043657 = 1043686
47 + 1043639 = 1043686
89 + 1043597 = 1043686
173 + 1043513 = 1043686
197 + 1043489 = 1043686
233 + 1043453 = 1043686

Showing the first eight; more decompositions exist.
