Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748978, here are decompositions:

5 + 8748973 = 8748978
89 + 8748889 = 8748978
97 + 8748881 = 8748978
101 + 8748877 = 8748978
131 + 8748847 = 8748978
137 + 8748841 = 8748978
151 + 8748827 = 8748978
157 + 8748821 = 8748978

Showing the first eight; more decompositions exist.
