Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532512, here are decompositions:
- 5 + 31532507 = 31532512
- 23 + 31532489 = 31532512
- 83 + 31532429 = 31532512
- 173 + 31532339 = 31532512
- 233 + 31532279 = 31532512
- 251 + 31532261 = 31532512
- 293 + 31532219 = 31532512
- 449 + 31532063 = 31532512
Showing the first eight; more decompositions exist.
