Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4942, here are decompositions:
- 5 + 4937 = 4942
- 11 + 4931 = 4942
- 23 + 4919 = 4942
- 53 + 4889 = 4942
- 71 + 4871 = 4942
- 149 + 4793 = 4942
- 191 + 4751 = 4942
- 239 + 4703 = 4942
Showing the first eight; more decompositions exist.
