Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38942, here are decompositions:
- 19 + 38923 = 38942
- 103 + 38839 = 38942
- 109 + 38833 = 38942
- 139 + 38803 = 38942
- 151 + 38791 = 38942
- 193 + 38749 = 38942
- 229 + 38713 = 38942
- 271 + 38671 = 38942
Showing the first eight; more decompositions exist.
