Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124980, here are decompositions:
- 29 + 124951 = 124980
- 61 + 124919 = 124980
- 71 + 124909 = 124980
- 73 + 124907 = 124980
- 83 + 124897 = 124980
- 127 + 124853 = 124980
- 157 + 124823 = 124980
- 181 + 124799 = 124980
Showing the first eight; more decompositions exist.
