Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702402, here are decompositions:

31 + 8702371 = 8702402
43 + 8702359 = 8702402
61 + 8702341 = 8702402
73 + 8702329 = 8702402
151 + 8702251 = 8702402
223 + 8702179 = 8702402
229 + 8702173 = 8702402
271 + 8702131 = 8702402

Showing the first eight; more decompositions exist.
