Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684238, here are decompositions:

7 + 8684231 = 8684238
37 + 8684201 = 8684238
61 + 8684177 = 8684238
67 + 8684171 = 8684238
107 + 8684131 = 8684238
127 + 8684111 = 8684238
131 + 8684107 = 8684238
139 + 8684099 = 8684238

Showing the first eight; more decompositions exist.
