Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005920, here are decompositions:

7 + 1005913 = 1005920
37 + 1005883 = 1005920
211 + 1005709 = 1005920
241 + 1005679 = 1005920
277 + 1005643 = 1005920
283 + 1005637 = 1005920
367 + 1005553 = 1005920
379 + 1005541 = 1005920

Showing the first eight; more decompositions exist.
