Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4618, here are decompositions:
- 71 + 4547 = 4618
- 101 + 4517 = 4618
- 137 + 4481 = 4618
- 167 + 4451 = 4618
- 197 + 4421 = 4618
- 227 + 4391 = 4618
- 269 + 4349 = 4618
- 281 + 4337 = 4618
Showing the first eight; more decompositions exist.
