Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008782, here are decompositions:

3 + 1008779 = 1008782
193 + 1008589 = 1008782
211 + 1008571 = 1008782
241 + 1008541 = 1008782
283 + 1008499 = 1008782
331 + 1008451 = 1008782
349 + 1008433 = 1008782
373 + 1008409 = 1008782

Showing the first eight; more decompositions exist.
