Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4988, here are decompositions:
- 19 + 4969 = 4988
- 31 + 4957 = 4988
- 37 + 4951 = 4988
- 79 + 4909 = 4988
- 127 + 4861 = 4988
- 157 + 4831 = 4988
- 199 + 4789 = 4988
- 229 + 4759 = 4988
Showing the first eight; more decompositions exist.
