Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015782, here are decompositions:

13 + 1015769 = 1015782
29 + 1015753 = 1015782
43 + 1015739 = 1015782
59 + 1015723 = 1015782
73 + 1015709 = 1015782
179 + 1015603 = 1015782
181 + 1015601 = 1015782
211 + 1015571 = 1015782

Showing the first eight; more decompositions exist.
