Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51930, here are decompositions:
- 17 + 51913 = 51930
- 23 + 51907 = 51930
- 31 + 51899 = 51930
- 37 + 51893 = 51930
- 59 + 51871 = 51930
- 61 + 51869 = 51930
- 71 + 51859 = 51930
- 101 + 51829 = 51930
Showing the first eight; more decompositions exist.
