Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8418, here are decompositions:

29 + 8389 = 8418
31 + 8387 = 8418
41 + 8377 = 8418
89 + 8329 = 8418
101 + 8317 = 8418
107 + 8311 = 8418
127 + 8291 = 8418
131 + 8287 = 8418

Showing the first eight; more decompositions exist.
