Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746842, here are decompositions:

23 + 8746819 = 8746842
29 + 8746813 = 8746842
31 + 8746811 = 8746842
43 + 8746799 = 8746842
89 + 8746753 = 8746842
109 + 8746733 = 8746842
163 + 8746679 = 8746842
191 + 8746651 = 8746842

Showing the first eight; more decompositions exist.
