Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731806, here are decompositions:

19 + 8731787 = 8731806
23 + 8731783 = 8731806
29 + 8731777 = 8731806
43 + 8731763 = 8731806
107 + 8731699 = 8731806
163 + 8731643 = 8731806
179 + 8731627 = 8731806
197 + 8731609 = 8731806

Showing the first eight; more decompositions exist.
