Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545004, here are decompositions:
- 3 + 31545001 = 31545004
- 41 + 31544963 = 31545004
- 233 + 31544771 = 31545004
- 347 + 31544657 = 31545004
- 431 + 31544573 = 31545004
- 443 + 31544561 = 31545004
- 461 + 31544543 = 31545004
- 587 + 31544417 = 31545004
Showing the first eight; more decompositions exist.
