Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748990, here are decompositions:

11 + 8748979 = 8748990
17 + 8748973 = 8748990
37 + 8748953 = 8748990
97 + 8748893 = 8748990
101 + 8748889 = 8748990
109 + 8748881 = 8748990
113 + 8748877 = 8748990
137 + 8748853 = 8748990

Showing the first eight; more decompositions exist.
