Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173280, here are decompositions:
- 7 + 173273 = 173280
- 13 + 173267 = 173280
- 17 + 173263 = 173280
- 31 + 173249 = 173280
- 61 + 173219 = 173280
- 71 + 173209 = 173280
- 73 + 173207 = 173280
- 89 + 173191 = 173280
Showing the first eight; more decompositions exist.
