Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005810, here are decompositions:

59 + 1005751 = 1005810
101 + 1005709 = 1005810
109 + 1005701 = 1005810
131 + 1005679 = 1005810
149 + 1005661 = 1005810
163 + 1005647 = 1005810
167 + 1005643 = 1005810
173 + 1005637 = 1005810

Showing the first eight; more decompositions exist.
