Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482400, here are decompositions:
- 11 + 31482389 = 31482400
- 107 + 31482293 = 31482400
- 227 + 31482173 = 31482400
- 233 + 31482167 = 31482400
- 281 + 31482119 = 31482400
- 311 + 31482089 = 31482400
- 317 + 31482083 = 31482400
- 353 + 31482047 = 31482400
Showing the first eight; more decompositions exist.
