Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124824, here are decompositions:
- 5 + 124819 = 124824
- 31 + 124793 = 124824
- 41 + 124783 = 124824
- 43 + 124781 = 124824
- 47 + 124777 = 124824
- 53 + 124771 = 124824
- 71 + 124753 = 124824
- 103 + 124721 = 124824
Showing the first eight; more decompositions exist.
