Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702388, here are decompositions:

17 + 8702371 = 8702388
29 + 8702359 = 8702388
47 + 8702341 = 8702388
59 + 8702329 = 8702388
61 + 8702327 = 8702388
109 + 8702279 = 8702388
137 + 8702251 = 8702388
157 + 8702231 = 8702388

Showing the first eight; more decompositions exist.
