Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31892, here are decompositions:
- 19 + 31873 = 31892
- 43 + 31849 = 31892
- 151 + 31741 = 31892
- 163 + 31729 = 31892
- 193 + 31699 = 31892
- 229 + 31663 = 31892
- 349 + 31543 = 31892
- 379 + 31513 = 31892
Showing the first eight; more decompositions exist.
