Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535200, here are decompositions:
- 17 + 31535183 = 31535200
- 29 + 31535171 = 31535200
- 167 + 31535033 = 31535200
- 239 + 31534961 = 31535200
- 401 + 31534799 = 31535200
- 443 + 31534757 = 31535200
- 449 + 31534751 = 31535200
- 461 + 31534739 = 31535200
Showing the first eight; more decompositions exist.
