Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24978, here are decompositions:
- 7 + 24971 = 24978
- 11 + 24967 = 24978
- 59 + 24919 = 24978
- 61 + 24917 = 24978
- 71 + 24907 = 24978
- 89 + 24889 = 24978
- 101 + 24877 = 24978
- 127 + 24851 = 24978
Showing the first eight; more decompositions exist.
