Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124320, here are decompositions:
- 11 + 124309 = 124320
- 17 + 124303 = 124320
- 19 + 124301 = 124320
- 23 + 124297 = 124320
- 29 + 124291 = 124320
- 43 + 124277 = 124320
- 71 + 124249 = 124320
- 73 + 124247 = 124320
Showing the first eight; more decompositions exist.
