Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623842, here are decompositions:

11 + 8623831 = 8623842
41 + 8623801 = 8623842
43 + 8623799 = 8623842
79 + 8623763 = 8623842
113 + 8623729 = 8623842
163 + 8623679 = 8623842
181 + 8623661 = 8623842
191 + 8623651 = 8623842

Showing the first eight; more decompositions exist.
