Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748040, here are decompositions:

23 + 8748017 = 8748040
29 + 8748011 = 8748040
53 + 8747987 = 8748040
83 + 8747957 = 8748040
107 + 8747933 = 8748040
113 + 8747927 = 8748040
137 + 8747903 = 8748040
149 + 8747891 = 8748040

Showing the first eight; more decompositions exist.
