Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31924, here are decompositions:
- 17 + 31907 = 31924
- 41 + 31883 = 31924
- 107 + 31817 = 31924
- 131 + 31793 = 31924
- 173 + 31751 = 31924
- 197 + 31727 = 31924
- 257 + 31667 = 31924
- 281 + 31643 = 31924
Showing the first eight; more decompositions exist.
