Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43140, here are decompositions:
- 7 + 43133 = 43140
- 23 + 43117 = 43140
- 37 + 43103 = 43140
- 47 + 43093 = 43140
- 73 + 43067 = 43140
- 89 + 43051 = 43140
- 103 + 43037 = 43140
- 127 + 43013 = 43140
Showing the first eight; more decompositions exist.
