Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701540, here are decompositions:

11 + 8701529 = 8701540
41 + 8701499 = 8701540
47 + 8701493 = 8701540
83 + 8701457 = 8701540
131 + 8701409 = 8701540
137 + 8701403 = 8701540
149 + 8701391 = 8701540
173 + 8701367 = 8701540

Showing the first eight; more decompositions exist.
