Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529322, here are decompositions:
- 43 + 31529279 = 31529322
- 53 + 31529269 = 31529322
- 73 + 31529249 = 31529322
- 79 + 31529243 = 31529322
- 103 + 31529219 = 31529322
- 109 + 31529213 = 31529322
- 173 + 31529149 = 31529322
- 233 + 31529089 = 31529322
Showing the first eight; more decompositions exist.
