Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8424, here are decompositions:
- 5 + 8419 = 8424
- 37 + 8387 = 8424
- 47 + 8377 = 8424
- 61 + 8363 = 8424
- 71 + 8353 = 8424
- 107 + 8317 = 8424
- 113 + 8311 = 8424
- 127 + 8297 = 8424
Showing the first eight; more decompositions exist.
