Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747816, here are decompositions:

13 + 8747803 = 8747816
73 + 8747743 = 8747816
79 + 8747737 = 8747816
127 + 8747689 = 8747816
139 + 8747677 = 8747816
163 + 8747653 = 8747816
193 + 8747623 = 8747816
199 + 8747617 = 8747816

Showing the first eight; more decompositions exist.
