Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8004, here are decompositions:
- 11 + 7993 = 8004
- 41 + 7963 = 8004
- 53 + 7951 = 8004
- 67 + 7937 = 8004
- 71 + 7933 = 8004
- 97 + 7907 = 8004
- 103 + 7901 = 8004
- 127 + 7877 = 8004
Showing the first eight; more decompositions exist.
