Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751072, here are decompositions:

59 + 8751013 = 8751072
103 + 8750969 = 8751072
131 + 8750941 = 8751072
139 + 8750933 = 8751072
149 + 8750923 = 8751072
151 + 8750921 = 8751072
179 + 8750893 = 8751072
181 + 8750891 = 8751072

Showing the first eight; more decompositions exist.
