Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42284, here are decompositions:
- 3 + 42281 = 42284
- 61 + 42223 = 42284
- 97 + 42187 = 42284
- 103 + 42181 = 42284
- 127 + 42157 = 42284
- 211 + 42073 = 42284
- 223 + 42061 = 42284
- 241 + 42043 = 42284
Showing the first eight; more decompositions exist.
