Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610842, here are decompositions:

13 + 8610829 = 8610842
103 + 8610739 = 8610842
193 + 8610649 = 8610842
199 + 8610643 = 8610842
241 + 8610601 = 8610842
283 + 8610559 = 8610842
379 + 8610463 = 8610842
433 + 8610409 = 8610842

Showing the first eight; more decompositions exist.
