Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005866, here are decompositions:

157 + 1005709 = 1005866
223 + 1005643 = 1005866
229 + 1005637 = 1005866
313 + 1005553 = 1005866
373 + 1005493 = 1005866
409 + 1005457 = 1005866
439 + 1005427 = 1005866
457 + 1005409 = 1005866

Showing the first eight; more decompositions exist.
