Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758842, here are decompositions:

19 + 8758823 = 8758842
23 + 8758819 = 8758842
41 + 8758801 = 8758842
61 + 8758781 = 8758842
109 + 8758733 = 8758842
173 + 8758669 = 8758842
181 + 8758661 = 8758842
269 + 8758573 = 8758842

Showing the first eight; more decompositions exist.
