Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7408, here are decompositions:
- 59 + 7349 = 7408
- 101 + 7307 = 7408
- 179 + 7229 = 7408
- 197 + 7211 = 7408
- 257 + 7151 = 7408
- 281 + 7127 = 7408
- 389 + 7019 = 7408
- 431 + 6977 = 7408
Showing the first eight; more decompositions exist.
