Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531090, here are decompositions:
- 11 + 31531079 = 31531090
- 89 + 31531001 = 31531090
- 113 + 31530977 = 31531090
- 131 + 31530959 = 31531090
- 197 + 31530893 = 31531090
- 257 + 31530833 = 31531090
- 263 + 31530827 = 31531090
- 293 + 31530797 = 31531090
Showing the first eight; more decompositions exist.
