Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7974, here are decompositions:
- 11 + 7963 = 7974
- 23 + 7951 = 7974
- 37 + 7937 = 7974
- 41 + 7933 = 7974
- 47 + 7927 = 7974
- 67 + 7907 = 7974
- 73 + 7901 = 7974
- 97 + 7877 = 7974
Showing the first eight; more decompositions exist.
