Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42290, here are decompositions:
- 7 + 42283 = 42290
- 67 + 42223 = 42290
- 97 + 42193 = 42290
- 103 + 42187 = 42290
- 109 + 42181 = 42290
- 151 + 42139 = 42290
- 229 + 42061 = 42290
- 271 + 42019 = 42290
Showing the first eight; more decompositions exist.
