Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31942, here are decompositions:
- 59 + 31883 = 31942
- 83 + 31859 = 31942
- 149 + 31793 = 31942
- 173 + 31769 = 31942
- 191 + 31751 = 31942
- 293 + 31649 = 31942
- 359 + 31583 = 31942
- 401 + 31541 = 31942
Showing the first eight; more decompositions exist.
