Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702486, here are decompositions:

3 + 8702483 = 8702486
127 + 8702359 = 8702486
157 + 8702329 = 8702486
307 + 8702179 = 8702486
313 + 8702173 = 8702486
337 + 8702149 = 8702486
349 + 8702137 = 8702486
379 + 8702107 = 8702486

Showing the first eight; more decompositions exist.
