Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42824, here are decompositions:
- 3 + 42821 = 42824
- 31 + 42793 = 42824
- 37 + 42787 = 42824
- 73 + 42751 = 42824
- 97 + 42727 = 42824
- 127 + 42697 = 42824
- 157 + 42667 = 42824
- 181 + 42643 = 42824
Showing the first eight; more decompositions exist.
