Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19264, here are decompositions:
- 5 + 19259 = 19264
- 53 + 19211 = 19264
- 83 + 19181 = 19264
- 101 + 19163 = 19264
- 107 + 19157 = 19264
- 191 + 19073 = 19264
- 227 + 19037 = 19264
- 233 + 19031 = 19264
Showing the first eight; more decompositions exist.
