Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85942, here are decompositions:
- 11 + 85931 = 85942
- 53 + 85889 = 85942
- 89 + 85853 = 85942
- 113 + 85829 = 85942
- 149 + 85793 = 85942
- 191 + 85751 = 85942
- 239 + 85703 = 85942
- 251 + 85691 = 85942
Showing the first eight; more decompositions exist.
