Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618402, here are decompositions:
- 41 + 31618361 = 31618402
- 83 + 31618319 = 31618402
- 113 + 31618289 = 31618402
- 191 + 31618211 = 31618402
- 239 + 31618163 = 31618402
- 269 + 31618133 = 31618402
- 281 + 31618121 = 31618402
- 353 + 31618049 = 31618402
Showing the first eight; more decompositions exist.
