Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170880, here are decompositions:
- 7 + 170873 = 170880
- 23 + 170857 = 170880
- 29 + 170851 = 170880
- 37 + 170843 = 170880
- 43 + 170837 = 170880
- 53 + 170827 = 170880
- 67 + 170813 = 170880
- 71 + 170809 = 170880
Showing the first eight; more decompositions exist.
