Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535536, here are decompositions:
- 107 + 31535429 = 31535536
- 113 + 31535423 = 31535536
- 317 + 31535219 = 31535536
- 353 + 31535183 = 31535536
- 479 + 31535057 = 31535536
- 503 + 31535033 = 31535536
- 797 + 31534739 = 31535536
- 827 + 31534709 = 31535536
Showing the first eight; more decompositions exist.
