Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624398, here are decompositions:
- 11 + 31624387 = 31624398
- 31 + 31624367 = 31624398
- 41 + 31624357 = 31624398
- 59 + 31624339 = 31624398
- 61 + 31624337 = 31624398
- 67 + 31624331 = 31624398
- 181 + 31624217 = 31624398
- 251 + 31624147 = 31624398
Showing the first eight; more decompositions exist.
