Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97940, here are decompositions:
- 13 + 97927 = 97940
- 61 + 97879 = 97940
- 79 + 97861 = 97940
- 97 + 97843 = 97940
- 127 + 97813 = 97940
- 151 + 97789 = 97940
- 163 + 97777 = 97940
- 211 + 97729 = 97940
Showing the first eight; more decompositions exist.
