Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8364, here are decompositions:
- 11 + 8353 = 8364
- 47 + 8317 = 8364
- 53 + 8311 = 8364
- 67 + 8297 = 8364
- 71 + 8293 = 8364
- 73 + 8291 = 8364
- 101 + 8263 = 8364
- 127 + 8237 = 8364
Showing the first eight; more decompositions exist.
