Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624270, here are decompositions:
- 53 + 31624217 = 31624270
- 257 + 31624013 = 31624270
- 269 + 31624001 = 31624270
- 281 + 31623989 = 31624270
- 311 + 31623959 = 31624270
- 317 + 31623953 = 31624270
- 383 + 31623887 = 31624270
- 449 + 31623821 = 31624270
Showing the first eight; more decompositions exist.
