Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005872, here are decompositions:

163 + 1005709 = 1005872
193 + 1005679 = 1005872
211 + 1005661 = 1005872
229 + 1005643 = 1005872
331 + 1005541 = 1005872
379 + 1005493 = 1005872
433 + 1005439 = 1005872
463 + 1005409 = 1005872

Showing the first eight; more decompositions exist.
