Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84238, here are decompositions:
- 17 + 84221 = 84238
- 47 + 84191 = 84238
- 59 + 84179 = 84238
- 101 + 84137 = 84238
- 107 + 84131 = 84238
- 149 + 84089 = 84238
- 179 + 84059 = 84238
- 191 + 84047 = 84238
Showing the first eight; more decompositions exist.
