Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531450, here are decompositions:
- 29 + 31531421 = 31531450
- 47 + 31531403 = 31531450
- 149 + 31531301 = 31531450
- 179 + 31531271 = 31531450
- 233 + 31531217 = 31531450
- 311 + 31531139 = 31531450
- 449 + 31531001 = 31531450
- 491 + 31530959 = 31531450
Showing the first eight; more decompositions exist.
