Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005876, here are decompositions:

43 + 1005833 = 1005876
167 + 1005709 = 1005876
197 + 1005679 = 1005876
199 + 1005677 = 1005876
229 + 1005647 = 1005876
233 + 1005643 = 1005876
239 + 1005637 = 1005876
257 + 1005619 = 1005876

Showing the first eight; more decompositions exist.
