Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42288, here are decompositions:
- 5 + 42283 = 42288
- 7 + 42281 = 42288
- 31 + 42257 = 42288
- 61 + 42227 = 42288
- 67 + 42221 = 42288
- 79 + 42209 = 42288
- 101 + 42187 = 42288
- 107 + 42181 = 42288
Showing the first eight; more decompositions exist.
