Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544740, here are decompositions:
- 23 + 31544717 = 31544740
- 83 + 31544657 = 31544740
- 167 + 31544573 = 31544740
- 179 + 31544561 = 31544740
- 197 + 31544543 = 31544740
- 347 + 31544393 = 31544740
- 443 + 31544297 = 31544740
- 569 + 31544171 = 31544740
Showing the first eight; more decompositions exist.
