Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748986, here are decompositions:

7 + 8748979 = 8748986
13 + 8748973 = 8748986
97 + 8748889 = 8748986
109 + 8748877 = 8748986
139 + 8748847 = 8748986
199 + 8748787 = 8748986
277 + 8748709 = 8748986
313 + 8748673 = 8748986

Showing the first eight; more decompositions exist.
