Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89840, here are decompositions:
- 7 + 89833 = 89840
- 19 + 89821 = 89840
- 31 + 89809 = 89840
- 43 + 89797 = 89840
- 61 + 89779 = 89840
- 73 + 89767 = 89840
- 151 + 89689 = 89840
- 181 + 89659 = 89840
Showing the first eight; more decompositions exist.
