Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545250, here are decompositions:
- 17 + 31545233 = 31545250
- 29 + 31545221 = 31545250
- 59 + 31545191 = 31545250
- 131 + 31545119 = 31545250
- 167 + 31545083 = 31545250
- 227 + 31545023 = 31545250
- 281 + 31544969 = 31545250
- 431 + 31544819 = 31545250
Showing the first eight; more decompositions exist.
