Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545718, here are decompositions:
- 5 + 31545713 = 31545718
- 89 + 31545629 = 31545718
- 107 + 31545611 = 31545718
- 311 + 31545407 = 31545718
- 317 + 31545401 = 31545718
- 389 + 31545329 = 31545718
- 401 + 31545317 = 31545718
- 419 + 31545299 = 31545718
Showing the first eight; more decompositions exist.
