Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532328, here are decompositions:
- 5 + 31532323 = 31532328
- 59 + 31532269 = 31532328
- 67 + 31532261 = 31532328
- 101 + 31532227 = 31532328
- 109 + 31532219 = 31532328
- 211 + 31532117 = 31532328
- 239 + 31532089 = 31532328
- 257 + 31532071 = 31532328
Showing the first eight; more decompositions exist.
