Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005940, here are decompositions:

3 + 1005937 = 1005940
29 + 1005911 = 1005940
107 + 1005833 = 1005940
113 + 1005827 = 1005940
179 + 1005761 = 1005940
239 + 1005701 = 1005940
263 + 1005677 = 1005940
293 + 1005647 = 1005940

Showing the first eight; more decompositions exist.
