Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458336, here are decompositions:
- 5 + 31458331 = 31458336
- 37 + 31458299 = 31458336
- 59 + 31458277 = 31458336
- 97 + 31458239 = 31458336
- 139 + 31458197 = 31458336
- 149 + 31458187 = 31458336
- 163 + 31458173 = 31458336
- 167 + 31458169 = 31458336
Showing the first eight; more decompositions exist.
