Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10402, here are decompositions:
- 3 + 10399 = 10402
- 11 + 10391 = 10402
- 59 + 10343 = 10402
- 71 + 10331 = 10402
- 89 + 10313 = 10402
- 101 + 10301 = 10402
- 113 + 10289 = 10402
- 131 + 10271 = 10402
Showing the first eight; more decompositions exist.
