Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005782, here are decompositions:

31 + 1005751 = 1005782
73 + 1005709 = 1005782
103 + 1005679 = 1005782
139 + 1005643 = 1005782
163 + 1005619 = 1005782
229 + 1005553 = 1005782
241 + 1005541 = 1005782
373 + 1005409 = 1005782

Showing the first eight; more decompositions exist.
