Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618318, here are decompositions:
- 29 + 31618289 = 31618318
- 107 + 31618211 = 31618318
- 131 + 31618187 = 31618318
- 191 + 31618127 = 31618318
- 197 + 31618121 = 31618318
- 257 + 31618061 = 31618318
- 269 + 31618049 = 31618318
- 317 + 31618001 = 31618318
Showing the first eight; more decompositions exist.
