Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4978, here are decompositions:
- 5 + 4973 = 4978
- 11 + 4967 = 4978
- 41 + 4937 = 4978
- 47 + 4931 = 4978
- 59 + 4919 = 4978
- 89 + 4889 = 4978
- 101 + 4877 = 4978
- 107 + 4871 = 4978
Showing the first eight; more decompositions exist.
