Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17880, here are decompositions:
- 17 + 17863 = 17880
- 29 + 17851 = 17880
- 41 + 17839 = 17880
- 43 + 17837 = 17880
- 53 + 17827 = 17880
- 73 + 17807 = 17880
- 89 + 17791 = 17880
- 97 + 17783 = 17880
Showing the first eight; more decompositions exist.
