Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15536, here are decompositions:
- 43 + 15493 = 15536
- 97 + 15439 = 15536
- 109 + 15427 = 15536
- 163 + 15373 = 15536
- 223 + 15313 = 15536
- 229 + 15307 = 15536
- 277 + 15259 = 15536
- 337 + 15199 = 15536
Showing the first eight; more decompositions exist.
