Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539336, here are decompositions:
- 5 + 31539331 = 31539336
- 7 + 31539329 = 31539336
- 47 + 31539289 = 31539336
- 53 + 31539283 = 31539336
- 107 + 31539229 = 31539336
- 173 + 31539163 = 31539336
- 193 + 31539143 = 31539336
- 263 + 31539073 = 31539336
Showing the first eight; more decompositions exist.
