Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42950, here are decompositions:
- 7 + 42943 = 42950
- 13 + 42937 = 42950
- 97 + 42853 = 42950
- 109 + 42841 = 42950
- 157 + 42793 = 42950
- 163 + 42787 = 42950
- 199 + 42751 = 42950
- 223 + 42727 = 42950
Showing the first eight; more decompositions exist.
