Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618630, here are decompositions:
- 83 + 31618547 = 31618630
- 167 + 31618463 = 31618630
- 227 + 31618403 = 31618630
- 269 + 31618361 = 31618630
- 311 + 31618319 = 31618630
- 419 + 31618211 = 31618630
- 431 + 31618199 = 31618630
- 443 + 31618187 = 31618630
Showing the first eight; more decompositions exist.
