Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4986, here are decompositions:
- 13 + 4973 = 4986
- 17 + 4969 = 4986
- 19 + 4967 = 4986
- 29 + 4957 = 4986
- 43 + 4943 = 4986
- 53 + 4933 = 4986
- 67 + 4919 = 4986
- 83 + 4903 = 4986
Showing the first eight; more decompositions exist.
