Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627402, here are decompositions:

31 + 8627371 = 8627402
61 + 8627341 = 8627402
73 + 8627329 = 8627402
103 + 8627299 = 8627402
151 + 8627251 = 8627402
211 + 8627191 = 8627402
229 + 8627173 = 8627402
241 + 8627161 = 8627402

Showing the first eight; more decompositions exist.
