Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000782, here are decompositions:

5 + 1000777 = 1000782
19 + 1000763 = 1000782
59 + 1000723 = 1000782
61 + 1000721 = 1000782
103 + 1000679 = 1000782
113 + 1000669 = 1000782
131 + 1000651 = 1000782
163 + 1000619 = 1000782

Showing the first eight; more decompositions exist.
