Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43870, here are decompositions:
- 3 + 43867 = 43870
- 17 + 43853 = 43870
- 83 + 43787 = 43870
- 89 + 43781 = 43870
- 149 + 43721 = 43870
- 179 + 43691 = 43870
- 257 + 43613 = 43870
- 263 + 43607 = 43870
Showing the first eight; more decompositions exist.
