Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758782, here are decompositions:

5 + 8758777 = 8758782
61 + 8758721 = 8758782
113 + 8758669 = 8758782
199 + 8758583 = 8758782
233 + 8758549 = 8758782
269 + 8758513 = 8758782
271 + 8758511 = 8758782
281 + 8758501 = 8758782

Showing the first eight; more decompositions exist.
