Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41978, here are decompositions:
- 19 + 41959 = 41978
- 31 + 41947 = 41978
- 37 + 41941 = 41978
- 67 + 41911 = 41978
- 127 + 41851 = 41978
- 241 + 41737 = 41978
- 331 + 41647 = 41978
- 337 + 41641 = 41978
Showing the first eight; more decompositions exist.
