Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720262, here are decompositions:

29 + 8720233 = 8720262
71 + 8720191 = 8720262
73 + 8720189 = 8720262
101 + 8720161 = 8720262
149 + 8720113 = 8720262
151 + 8720111 = 8720262
181 + 8720081 = 8720262
191 + 8720071 = 8720262

Showing the first eight; more decompositions exist.
