Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564918, here are decompositions:
- 137 + 31564781 = 31564918
- 149 + 31564769 = 31564918
- 179 + 31564739 = 31564918
- 197 + 31564721 = 31564918
- 257 + 31564661 = 31564918
- 269 + 31564649 = 31564918
- 401 + 31564517 = 31564918
- 479 + 31564439 = 31564918
Showing the first eight; more decompositions exist.
