Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126518, here are decompositions:
- 19 + 126499 = 126518
- 31 + 126487 = 126518
- 37 + 126481 = 126518
- 61 + 126457 = 126518
- 97 + 126421 = 126518
- 181 + 126337 = 126518
- 211 + 126307 = 126518
- 277 + 126241 = 126518
Showing the first eight; more decompositions exist.
