Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445084, here are decompositions:
- 43 + 31445041 = 31445084
- 67 + 31445017 = 31445084
- 193 + 31444891 = 31445084
- 241 + 31444843 = 31445084
- 271 + 31444813 = 31445084
- 277 + 31444807 = 31445084
- 283 + 31444801 = 31445084
- 313 + 31444771 = 31445084
Showing the first eight; more decompositions exist.
