Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97978, here are decompositions:
- 5 + 97973 = 97978
- 11 + 97967 = 97978
- 17 + 97961 = 97978
- 47 + 97931 = 97978
- 59 + 97919 = 97978
- 107 + 97871 = 97978
- 131 + 97847 = 97978
- 137 + 97841 = 97978
Showing the first eight; more decompositions exist.
