Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624176, here are decompositions:
- 29 + 31624147 = 31624176
- 47 + 31624129 = 31624176
- 107 + 31624069 = 31624176
- 163 + 31624013 = 31624176
- 173 + 31624003 = 31624176
- 193 + 31623983 = 31624176
- 197 + 31623979 = 31624176
- 223 + 31623953 = 31624176
Showing the first eight; more decompositions exist.
