Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005992, here are decompositions:

3 + 1005989 = 1005992
61 + 1005931 = 1005992
79 + 1005913 = 1005992
109 + 1005883 = 1005992
241 + 1005751 = 1005992
283 + 1005709 = 1005992
313 + 1005679 = 1005992
331 + 1005661 = 1005992

Showing the first eight; more decompositions exist.
