Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706842, here are decompositions:

13 + 8706829 = 8706842
19 + 8706823 = 8706842
229 + 8706613 = 8706842
379 + 8706463 = 8706842
439 + 8706403 = 8706842
601 + 8706241 = 8706842
673 + 8706169 = 8706842
769 + 8706073 = 8706842

Showing the first eight; more decompositions exist.
