Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650842, here are decompositions:

29 + 8650813 = 8650842
43 + 8650799 = 8650842
89 + 8650753 = 8650842
139 + 8650703 = 8650842
173 + 8650669 = 8650842
191 + 8650651 = 8650842
281 + 8650561 = 8650842
283 + 8650559 = 8650842

Showing the first eight; more decompositions exist.
