Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750220, here are decompositions:

23 + 8750197 = 8750220
29 + 8750191 = 8750220
43 + 8750177 = 8750220
97 + 8750123 = 8750220
113 + 8750107 = 8750220
151 + 8750069 = 8750220
173 + 8750047 = 8750220
181 + 8750039 = 8750220

Showing the first eight; more decompositions exist.
