Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720202, here are decompositions:

11 + 8720191 = 8720202
13 + 8720189 = 8720202
31 + 8720171 = 8720202
41 + 8720161 = 8720202
83 + 8720119 = 8720202
89 + 8720113 = 8720202
131 + 8720071 = 8720202
241 + 8719961 = 8720202

Showing the first eight; more decompositions exist.
