Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89870, here are decompositions:
- 3 + 89867 = 89870
- 31 + 89839 = 89870
- 37 + 89833 = 89870
- 61 + 89809 = 89870
- 73 + 89797 = 89870
- 103 + 89767 = 89870
- 181 + 89689 = 89870
- 199 + 89671 = 89870
Showing the first eight; more decompositions exist.
