Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027782, here are decompositions:

5 + 1027777 = 1027782
23 + 1027759 = 1027782
29 + 1027753 = 1027782
31 + 1027751 = 1027782
43 + 1027739 = 1027782
79 + 1027703 = 1027782
89 + 1027693 = 1027782
103 + 1027679 = 1027782

Showing the first eight; more decompositions exist.
