Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4678, here are decompositions:
- 5 + 4673 = 4678
- 29 + 4649 = 4678
- 41 + 4637 = 4678
- 131 + 4547 = 4678
- 197 + 4481 = 4678
- 227 + 4451 = 4678
- 257 + 4421 = 4678
- 269 + 4409 = 4678
Showing the first eight; more decompositions exist.
