Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701582, here are decompositions:

5 + 8701577 = 8701582
11 + 8701571 = 8701582
23 + 8701559 = 8701582
53 + 8701529 = 8701582
83 + 8701499 = 8701582
89 + 8701493 = 8701582
173 + 8701409 = 8701582
179 + 8701403 = 8701582

Showing the first eight; more decompositions exist.
