Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748866, here are decompositions:

13 + 8748853 = 8748866
19 + 8748847 = 8748866
79 + 8748787 = 8748866
127 + 8748739 = 8748866
157 + 8748709 = 8748866
193 + 8748673 = 8748866
223 + 8748643 = 8748866
277 + 8748589 = 8748866

Showing the first eight; more decompositions exist.
