Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005786, here are decompositions:

107 + 1005679 = 1005786
109 + 1005677 = 1005786
139 + 1005647 = 1005786
149 + 1005637 = 1005786
167 + 1005619 = 1005786
193 + 1005593 = 1005786
233 + 1005553 = 1005786
283 + 1005503 = 1005786

Showing the first eight; more decompositions exist.
