Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42224, here are decompositions:
- 3 + 42221 = 42224
- 31 + 42193 = 42224
- 37 + 42187 = 42224
- 43 + 42181 = 42224
- 67 + 42157 = 42224
- 151 + 42073 = 42224
- 163 + 42061 = 42224
- 181 + 42043 = 42224
Showing the first eight; more decompositions exist.
