Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662786, here are decompositions:

3 + 8662783 = 8662786
17 + 8662769 = 8662786
137 + 8662649 = 8662786
233 + 8662553 = 8662786
269 + 8662517 = 8662786
389 + 8662397 = 8662786
443 + 8662343 = 8662786
449 + 8662337 = 8662786

Showing the first eight; more decompositions exist.
