Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624208, here are decompositions:
- 61 + 31624147 = 31624208
- 67 + 31624141 = 31624208
- 79 + 31624129 = 31624208
- 139 + 31624069 = 31624208
- 229 + 31623979 = 31624208
- 241 + 31623967 = 31624208
- 277 + 31623931 = 31624208
- 307 + 31623901 = 31624208
Showing the first eight; more decompositions exist.
