Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532838, here are decompositions:
- 5 + 31532833 = 31532838
- 61 + 31532777 = 31532838
- 89 + 31532749 = 31532838
- 101 + 31532737 = 31532838
- 151 + 31532687 = 31532838
- 179 + 31532659 = 31532838
- 199 + 31532639 = 31532838
- 241 + 31532597 = 31532838
Showing the first eight; more decompositions exist.
