Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545434, here are decompositions:
- 43 + 31545391 = 31545434
- 61 + 31545373 = 31545434
- 103 + 31545331 = 31545434
- 223 + 31545211 = 31545434
- 337 + 31545097 = 31545434
- 367 + 31545067 = 31545434
- 373 + 31545061 = 31545434
- 433 + 31545001 = 31545434
Showing the first eight; more decompositions exist.
