Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555348, here are decompositions:
- 17 + 31555331 = 31555348
- 29 + 31555319 = 31555348
- 59 + 31555289 = 31555348
- 89 + 31555259 = 31555348
- 137 + 31555211 = 31555348
- 191 + 31555157 = 31555348
- 239 + 31555109 = 31555348
- 269 + 31555079 = 31555348
Showing the first eight; more decompositions exist.
