Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51942, here are decompositions:
- 13 + 51929 = 51942
- 29 + 51913 = 51942
- 43 + 51899 = 51942
- 71 + 51871 = 51942
- 73 + 51869 = 51942
- 83 + 51859 = 51942
- 89 + 51853 = 51942
- 103 + 51839 = 51942
Showing the first eight; more decompositions exist.
