Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535668, here are decompositions:
- 11 + 31535657 = 31535668
- 29 + 31535639 = 31535668
- 239 + 31535429 = 31535668
- 251 + 31535417 = 31535668
- 257 + 31535411 = 31535668
- 347 + 31535321 = 31535668
- 449 + 31535219 = 31535668
- 587 + 31535081 = 31535668
Showing the first eight; more decompositions exist.
