Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748144, here are decompositions:

7 + 8748137 = 8748144
47 + 8748097 = 8748144
101 + 8748043 = 8748144
113 + 8748031 = 8748144
127 + 8748017 = 8748144
157 + 8747987 = 8748144
173 + 8747971 = 8748144
211 + 8747933 = 8748144

Showing the first eight; more decompositions exist.
