Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40860, here are decompositions:
- 7 + 40853 = 40860
- 11 + 40849 = 40860
- 13 + 40847 = 40860
- 19 + 40841 = 40860
- 31 + 40829 = 40860
- 37 + 40823 = 40860
- 41 + 40819 = 40860
- 47 + 40813 = 40860
Showing the first eight; more decompositions exist.
