Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493164, here are decompositions:
- 11 + 31493153 = 31493164
- 107 + 31493057 = 31493164
- 167 + 31492997 = 31493164
- 173 + 31492991 = 31493164
- 257 + 31492907 = 31493164
- 317 + 31492847 = 31493164
- 383 + 31492781 = 31493164
- 467 + 31492697 = 31493164
Showing the first eight; more decompositions exist.
