Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555310, here are decompositions:
- 13 + 31555297 = 31555310
- 43 + 31555267 = 31555310
- 67 + 31555243 = 31555310
- 139 + 31555171 = 31555310
- 211 + 31555099 = 31555310
- 229 + 31555081 = 31555310
- 349 + 31554961 = 31555310
- 421 + 31554889 = 31555310
Showing the first eight; more decompositions exist.
