Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91978, here are decompositions:
- 11 + 91967 = 91978
- 17 + 91961 = 91978
- 137 + 91841 = 91978
- 167 + 91811 = 91978
- 197 + 91781 = 91978
- 347 + 91631 = 91978
- 401 + 91577 = 91978
- 449 + 91529 = 91978
Showing the first eight; more decompositions exist.
