Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4688, here are decompositions:
- 31 + 4657 = 4688
- 37 + 4651 = 4688
- 67 + 4621 = 4688
- 97 + 4591 = 4688
- 127 + 4561 = 4688
- 139 + 4549 = 4688
- 181 + 4507 = 4688
- 241 + 4447 = 4688
Showing the first eight; more decompositions exist.
