Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42242, here are decompositions:
- 3 + 42239 = 42242
- 19 + 42223 = 42242
- 61 + 42181 = 42242
- 73 + 42169 = 42242
- 103 + 42139 = 42242
- 181 + 42061 = 42242
- 199 + 42043 = 42242
- 223 + 42019 = 42242
Showing the first eight; more decompositions exist.
