Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15436, here are decompositions:
- 23 + 15413 = 15436
- 53 + 15383 = 15436
- 59 + 15377 = 15436
- 107 + 15329 = 15436
- 137 + 15299 = 15436
- 149 + 15287 = 15436
- 167 + 15269 = 15436
- 173 + 15263 = 15436
Showing the first eight; more decompositions exist.
