Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120280, here are decompositions:
- 3 + 120277 = 120280
- 47 + 120233 = 120280
- 71 + 120209 = 120280
- 113 + 120167 = 120280
- 233 + 120047 = 120280
- 239 + 120041 = 120280
- 263 + 120017 = 120280
- 269 + 120011 = 120280
Showing the first eight; more decompositions exist.
