Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10420, here are decompositions:
- 29 + 10391 = 10420
- 83 + 10337 = 10420
- 89 + 10331 = 10420
- 107 + 10313 = 10420
- 131 + 10289 = 10420
- 149 + 10271 = 10420
- 167 + 10253 = 10420
- 173 + 10247 = 10420
Showing the first eight; more decompositions exist.
