Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761782, here are decompositions:

19 + 8761763 = 8761782
31 + 8761751 = 8761782
61 + 8761721 = 8761782
79 + 8761703 = 8761782
149 + 8761633 = 8761782
151 + 8761631 = 8761782
163 + 8761619 = 8761782
181 + 8761601 = 8761782

Showing the first eight; more decompositions exist.
