Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005830, here are decompositions:

3 + 1005827 = 1005830
79 + 1005751 = 1005830
151 + 1005679 = 1005830
193 + 1005637 = 1005830
211 + 1005619 = 1005830
277 + 1005553 = 1005830
337 + 1005493 = 1005830
349 + 1005481 = 1005830

Showing the first eight; more decompositions exist.
