Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15584, here are decompositions:
- 3 + 15581 = 15584
- 43 + 15541 = 15584
- 73 + 15511 = 15584
- 157 + 15427 = 15584
- 193 + 15391 = 15584
- 211 + 15373 = 15584
- 223 + 15361 = 15584
- 271 + 15313 = 15584
Showing the first eight; more decompositions exist.
