Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005918, here are decompositions:

5 + 1005913 = 1005918
7 + 1005911 = 1005918
97 + 1005821 = 1005918
157 + 1005761 = 1005918
167 + 1005751 = 1005918
239 + 1005679 = 1005918
241 + 1005677 = 1005918
257 + 1005661 = 1005918

Showing the first eight; more decompositions exist.
