Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672782, here are decompositions:

3 + 8672779 = 8672782
59 + 8672723 = 8672782
263 + 8672519 = 8672782
269 + 8672513 = 8672782
281 + 8672501 = 8672782
311 + 8672471 = 8672782
353 + 8672429 = 8672782
359 + 8672423 = 8672782

Showing the first eight; more decompositions exist.
