Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15560, here are decompositions:
- 19 + 15541 = 15560
- 67 + 15493 = 15560
- 109 + 15451 = 15560
- 199 + 15361 = 15560
- 211 + 15349 = 15560
- 229 + 15331 = 15560
- 241 + 15319 = 15560
- 271 + 15289 = 15560
Showing the first eight; more decompositions exist.
