Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126408, here are decompositions:
- 11 + 126397 = 126408
- 59 + 126349 = 126408
- 67 + 126341 = 126408
- 71 + 126337 = 126408
- 97 + 126311 = 126408
- 101 + 126307 = 126408
- 137 + 126271 = 126408
- 151 + 126257 = 126408
Showing the first eight; more decompositions exist.
