Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83942, here are decompositions:
- 3 + 83939 = 83942
- 31 + 83911 = 83942
- 73 + 83869 = 83942
- 109 + 83833 = 83942
- 151 + 83791 = 83942
- 181 + 83761 = 83942
- 223 + 83719 = 83942
- 241 + 83701 = 83942
Showing the first eight; more decompositions exist.
