Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49986, here are decompositions:
- 29 + 49957 = 49986
- 43 + 49943 = 49986
- 47 + 49939 = 49986
- 59 + 49927 = 49986
- 67 + 49919 = 49986
- 109 + 49877 = 49986
- 163 + 49823 = 49986
- 179 + 49807 = 49986
Showing the first eight; more decompositions exist.
