Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51940, here are decompositions:
- 11 + 51929 = 51940
- 41 + 51899 = 51940
- 47 + 51893 = 51940
- 71 + 51869 = 51940
- 101 + 51839 = 51940
- 113 + 51827 = 51940
- 137 + 51803 = 51940
- 173 + 51767 = 51940
Showing the first eight; more decompositions exist.
