Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80782, here are decompositions:

3 + 80779 = 80782
5 + 80777 = 80782
101 + 80681 = 80782
113 + 80669 = 80782
131 + 80651 = 80782
179 + 80603 = 80782
269 + 80513 = 80782
293 + 80489 = 80782

Showing the first eight; more decompositions exist.
