Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515322, here are decompositions:
- 5 + 31515317 = 31515322
- 11 + 31515311 = 31515322
- 23 + 31515299 = 31515322
- 53 + 31515269 = 31515322
- 173 + 31515149 = 31515322
- 281 + 31515041 = 31515322
- 353 + 31514969 = 31515322
- 359 + 31514963 = 31515322
Showing the first eight; more decompositions exist.
