Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706672, here are decompositions:

5 + 8706667 = 8706672
59 + 8706613 = 8706672
61 + 8706611 = 8706672
103 + 8706569 = 8706672
193 + 8706479 = 8706672
211 + 8706461 = 8706672
269 + 8706403 = 8706672
311 + 8706361 = 8706672

Showing the first eight; more decompositions exist.
