Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454258, here are decompositions:
- 37 + 31454221 = 31454258
- 61 + 31454197 = 31454258
- 67 + 31454191 = 31454258
- 97 + 31454161 = 31454258
- 109 + 31454149 = 31454258
- 181 + 31454077 = 31454258
- 349 + 31453909 = 31454258
- 379 + 31453879 = 31454258
Showing the first eight; more decompositions exist.
