Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535152, here are decompositions:
- 29 + 31535123 = 31535152
- 71 + 31535081 = 31535152
- 191 + 31534961 = 31535152
- 239 + 31534913 = 31535152
- 281 + 31534871 = 31535152
- 353 + 31534799 = 31535152
- 401 + 31534751 = 31535152
- 443 + 31534709 = 31535152
Showing the first eight; more decompositions exist.
