Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648782, here are decompositions:

3 + 8648779 = 8648782
41 + 8648741 = 8648782
53 + 8648729 = 8648782
239 + 8648543 = 8648782
251 + 8648531 = 8648782
269 + 8648513 = 8648782
281 + 8648501 = 8648782
449 + 8648333 = 8648782

Showing the first eight; more decompositions exist.
