Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122424, here are decompositions:
- 23 + 122401 = 122424
- 31 + 122393 = 122424
- 37 + 122387 = 122424
- 61 + 122363 = 122424
- 97 + 122327 = 122424
- 101 + 122323 = 122424
- 103 + 122321 = 122424
- 151 + 122273 = 122424
Showing the first eight; more decompositions exist.
