Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748072, here are decompositions:

29 + 8748043 = 8748072
41 + 8748031 = 8748072
61 + 8748011 = 8748072
71 + 8748001 = 8748072
101 + 8747971 = 8748072
131 + 8747941 = 8748072
139 + 8747933 = 8748072
181 + 8747891 = 8748072

Showing the first eight; more decompositions exist.
