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.
