Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51980, here are decompositions:
- 3 + 51977 = 51980
- 7 + 51973 = 51980
- 31 + 51949 = 51980
- 67 + 51913 = 51980
- 73 + 51907 = 51980
- 109 + 51871 = 51980
- 127 + 51853 = 51980
- 151 + 51829 = 51980
Showing the first eight; more decompositions exist.
